    Gallstones consist of calcium salts and cholesterol crystals, arrayed on a matrix of gallbladder mucin (GBM), and regulatory proteins like calcium-binding protein (CBP). To determine if interactions between CBP and GBM follow a biomineralization scheme, their mutual binding and effects on CaHPO4

    Gallstones consist of calcium salts and cholesterol crystals, arrayed on a matrix of gallbladder mucin (GBM), and regulatory proteins like calcium-binding protein (CBP). To determine if interactions between CBP and GBM follow a biomineralization scheme, their mutual binding and effects on CaHPO4 precipitation were studied. Binding of CBP to GBM was assessed by inhibition of the fluorescence of the complex of GBM with bis-1,8-anilinonaphthalene sulfonic acid (bis-ANS). The effects of the proteins on precipitation of CaHPO4 were assessed by nephelometry and gravimetry. Precipitates were analyzed for calcium, phosphate, and protein. CBP and bis-ANS competitively displaced each other from 30 binding sites on mucin, with a 1:1 stoichiometry and similar affinity. The rate of precipitation of CaHPO4 was retarded by mucin and CBP. Precipitate mass was unaffected by GBM alone but decreased with the addition of CBP. Complexing CBP with GBM abolished or moderated this latter effect, altered precipitate morphology, and changed the stoichiometric ratios of Ca to PO4 in the precipitates from 1:1 to 3:2. Mucin and CBP were incorporated into the precipitates. These studies suggest that the formation of calcium-containing gallstones is a biomineralization process regulated by both GBM and CBP.

    Conclusion: Duplication of the gallbladder is a rare congenital abnormality, which requires special attention to the biliary ductal and arterial anatomy. Laparoscopic cholecystectomy with intraoperative cholangiography is the appropriate treatment in a symptomatic gallbladder. The removal of an asymptomatic double gallbladder remains controversial.

  5. Incidental gallbladder cancer: what management?

    Full Text Available Gallbladder cancer (GBC represents 3.8% of all gastrointestinal cancers and usually known to be of a poor prognosis. In 0.2–2.9% of cases, this cancer is found in cholecystectomy specimens. A better understanding of spread mode of this tumor helps a better surgical management. The aim of the present review is to underline the management of GBC based on the comprehension of risk factors and anatomic features. A Medline, PubMed database search was performed to identify articles published from 2000 to 2011 using the keywords ‘carcinoma of gallbladder’, ‘incidental gallbladder cancer’, ‘gallbladder neoplasm’ and ‘cholecystectomy’. Some pathological situations such as chronic lithiasis and biliopancreatic junction abnormalities have been clearly identified as predisposing to GBC. Laparoscopy increases peritoneal and parietal tumor dissemination, thus, it should not be performed when GBC is suspected. Most determinant prognostic factors are nodal, perineural and venous involvement, invasion of the cystic duct and the tumor differentiation. The simple cholecystectomy is sufficient for tumors classified as T1a; for other cancers exceeding the muscularis, radical re-resection is required due to the high risk of recurrence. This aggressive surgery improved the overall survival of patients. There is still no standard adjuvant treatment; patients should be included in prospective trials.

    Carcinoma gallbladder (CaGb) is a rare disease. The aetiology of CaGb is yet not known. However the risk of CaGb is increased in anomalous pancreaticobiliary duct junction (APBDJ), gall stones, xanthogranulomatus cholecystitis, calcified or porcelain gallbladder, cholelithiasis with typhoid carriers, gallbladder adenoma, red meat consumption and tobacco uses. There are protective effects of vegetables on CaGb. Most of the cases present with advanced disease. In early carcinoma of a gallbladder sign and symptoms mimic benign disease. The diagnosis is established by ultrasonography, computerized tomography and guided fine needle aspiration cytology (FNAC). Biochemical tests are of very little value in making a diagnosis. The treatment depends on the clinical stage at presentation. Surgery offers the best chance of cure. In stage T1a, laparoscopic or open cholecystectomy alone is curative, and in T1b, cholecystectomy with hepatoduodenal lymph node dissection without combined resection of an adjacent organ is required. Segment S4a+5 hepatectomy combined with extrahepatic bile duct resection (BDR) and D2 lymph node dissection is a highly recommended operation for the treatment of T2 and T3 CaGb. The dye injection method is useful in determining the appropriate extent of hepatic resection for advanced CaGb. Resurgery is required only in those cases where tumour has invaded the serosa and/ or adjacent structures when diagnosed postoperatively. Biliary bypass is required for palliation. Prognosis depends on early diagnosis and appropriate surgical excision.

    PurposeTo investigate the feasibility of percutaneous gallbladder cryoablation (GBC) under CT guidance in a swine model with histopathologic correlation.Materials and MethodsInstitutional Animal Care and Use Committee approval was obtained for this study protocol. Five pigs underwent GBC. Under CT guidance, 3–4 cryoprobes were positioned percutaneously at the gallbladder margins. Thermocouple probes were placed percutaneously at the gallbladder fundus, neck, free wall, and gallbladder fossa. Two freeze–thaw cycles ranging from 10 to 26 min were performed. The subjects were sacrificed 5 h after cryoablation. The gallbladder and bile ducts were resected, stained, and examined microscopically.ResultsGBC was completed in all subjects. A 10-mm ablation margin was achieved beyond all gallbladder walls. Thermocouple probes reached at least −20 °C. Intra-procedural body temperature decreased to a minimum of 35 °C but recovered after the procedure. Intra- and post-procedural vital signs otherwise remained within physiologic parameters. Non-target ablation occurred in the stomach and colon of the first two subjects. Histology demonstrated complete denudation of the gallbladder epithelium, hemorrhage, and edema within the muscularis layer, and preservation of the microscopic architecture of the common bile duct in all cases.ConclusionPercutaneous gallbladder cryoablation is feasible, with adequate ablation margins obtained and histologic changes demonstrating transmural necrosis. Adjacent structures included in the ablation may require conservative ablation zones, hydrodissection, or continuous saline lavage.

    Ultrasonographic appearance of unorganized hyperechoic striations (UHS) has been observed in the canine gastric muscularis layer. The purpose of the study was to determine the prevalence, sonographic and postmortem histologic features, and to determine the clinical significance of canine gastric muscularis UHS. In the prospective study, 72 dogs were included. The presence of gastric muscularis UHS were reviewed to determine its distribution and location. In the retrospective study, 167 dogs that had both abdominal ultrasonography and necropsy were included. The prevalence of gastric muscularis UHS in dogs was 37.5% in the prospective and 5.4% in the retrospective studies respectively. The higher prevalence in prospective study was due to greater anticipation by the radiologists in search for gastric muscularis UHS. In the ventral gastric wall, the muscularis UHS were better defined when the gastric lumen was empty or non-distended, and were mostly parallel with the serosa when the gastric wall was distended (with gas or fluid). Visualization of the dorsal gastric wall was often obscured by gas shadowing from luminal gas. Histopathology was performed on eight dogs with gastric muscularis UHS, three of which had fibrous tissue observed with Masson's trichrome stain. Presence of gastric muscularis UHS in dogs may have been attributable to presence of incomplete interfaces between the inner oblique, middle circular and outer longitudinal layers of the gastric tunica muscularis or due to presence of fibrous tissue within the gastric muscularis layer. The clinical significance of canine gastric muscularis UHS is uncertain.

    Spontaneous perforation of the gallbladder is one complication of cholelithiasis. There is a greater occurence of free perforation in the peritoneal cavity with bilary pertonitis, followed by the perforation into the stomach, small intestine and colon. A single case of the nowadays rare spontaneous perforation in and through the abdominal wall will be reported. Spontaneous gallbladder perforation appears nearly asymptomatic in its clinical course because of absent biliary peritonitis. (orig.) [de

    Multiphoton microscopy (MPM) based on two-photon excited fluorescence (TPEF) and second harmonic generation (SHG) as a potential diagnostic tool is attractive. MPM can effectively provide information about morphological and biochemical changes in biological tissues at the molecular level. In this paper, we attempt to identify normal and cancerous human colorectal muscularis propria by multiphoton microscopy in different sections (both in transverse and longitudinal sections). The results show that MPM can display different microstructure changes in the transverse and longitudinal sections of colorectal muscularis propria. MPM also can quantitatively describe the alteration of collagen content between normal and cancerous muscle layers. These are important pathological findings that MPM images can bring more detailed complementary information about tissue architecture and cell morphology through observing the transverse and longitudinal sections of colorectal muscularis propria. This work demonstrates that MPM can be better for identifying the microstructural characteristics of normal and cancerous human colorectal muscularis propria in different sections. (paper)

    1988-01-01

    Thirty pigs underwent cystic duct occlusion by means of transcatheter endoluminal bipolar radiofrequency electrocoagulation under fluoroscopic guidance. Twenty animals subsequently underwent gallbladder ablation with alcohol and sotradecol; ten animals served as controls. Serial histologic blocking of the common bile duct, cystic duct, and gallbladder in all animals revealed no adverse effects of the sclerosants on the bile ducts or the structures adjacent to the gallbladder. The combination of 95% alcohol plus 3% sotradecol resulted in necrosis of the gallbladder mucosa within 2 weeks (two of two animals) and complete eradication of the mucosa and fibrotic obliteration of the gallbladder lumen within 8 weeks (six of eight animals)

    The aim of this study was to characterize the binding and functional properties of muscarinic cholinergic (MCh) and alpha 2-adrenergic receptors in the human ileum to provide insight into pharmacologic strategies for managing urinary and fecal incontinence after bladder and rectal replacement with intestinal segments. MCh and alpha 2-adrenergic binding sites were characterized in the epithelium and muscularis of eight human ileal segments with 3H-N-methylscopolamine and 3H-rauwolscine, respectively. The dissociation constant for 3H-N-methylscopolamine in the epithelium and muscularis was 0.32 +/- 0.07 nmol/L and 0.45 +/- 0.10 nmol/L, respectively (p = 0.32). The MCh receptor content was approximately eightfold greater in the muscularis compared with the epithelium (p = 0.008). The dissociation constant for 3H-rauwolscine in the muscularis and epithelium was 2.55 +/- 0.42 nmol/L and 2.03 +/- 0.19 nmol/L, respectively (p = 0.29). The alpha 2-adrenoceptor density was twofold greater in the epithelium compared with the muscularis (p = 0.05). Noncumulative concentration-response experiments were performed with carbachol, an MCh agonist, and UK-14304, a selective alpha 2-adrenergic agonist. The epithelium did not contract in the presence of high concentrations of carbachol and UK-14304. The muscularis preparations were responsive only to carbachol. The muscularis contains primarily MCh receptors mediating smooth muscle contraction. The alpha 2-adrenoceptors are localized primarily to the epithelium and may regulate water secretion in the intestine. The distribution and functional properties of ileal MCh and alpha 2-adrenergic receptors provide a theoretic basis for the treatment of incontinence after bladder and rectal replacement with intestinal segments

    This study was designed to evaluate the safety and efficacy of endoscopic excavation for esophageal subepithelial tumors originating from the muscularis propria. Forty-five patients with esophageal subepithelial tumors originating from the muscularis propria were treated with endoscopic excavation between January 2010 and June 2012. The key steps were: (1) making several dots around the tumor; (2) incising the mucosa along with the marker dots, and then seperating the tumor from the muscularis propria by using a hook knife or an insulated-tip knife; (3) closing the artificial ulcer with clips after the tumor was removed. The mean tumor diameter was 1.1 ± 0.6 cm. Endoscopic excavation was successfully performed in 43 out of 45 cases (95.6%), the other 2 cases were ligated with nylon rope. During the procedure perforation occurred in 4 (8.9%) patients, who recovered after conservative treatment. No massive bleeding or delayed bleeding occurred. Histologic diagnosis was obtained from 43 (95.6%) patients. Pathological diagnoses of these tumors were leiomyomas (38/43) and gastrointestinal stromal tumors (5/43). Endoscopic excavation is a safe and effective method for the treatment of small esophageal subepithelial tumors originating from the muscularis propria.

    To evaluate the efficacy, safety and feasibility of endoscopic full-thickness resection (EFR) for the treatment of gastric submucosal tumors (SMTs) arising from the muscularis propria. A total of 35 gastric SMTs arising from the muscularis propria layer were resected by EFR between January 2010 and September 2013. EFR consists of five major steps: injecting normal saline into the submucosa; pre-cutting the mucosal and submucosal layers around the lesion; making a circumferential incision as deep as the muscularis propria around the lesion using endoscopic submucosal dissection and an incision into the serosal layer around the lesion with a Hook knife; a full-thickness resection of the tumor, including the serosal layer with a Hook or IT knife; and closing the gastric wall with metallic clips. Of the 35 gastric SMTs, 14 were located at the fundus, and 21 at the corpus. EFR removed all of the SMTs successfully, and the complete resection rate was 100%. The mean operation time was 90 min (60-155 min), the mean hospitalization time was 6.0 d (4-10 d), and the mean tumor size was 2.8 cm (2.0-4.5 cm). Pathological examination confirmed the presence of gastric stromal tumors in 25 patients, leiomyomas in 7 and gastric autonomous nerve tumors in 2. No gastric bleeding, peritonitis or abdominal abscess occurred after EFR. Postoperative contrast roentgenography on the third day detected no contrast extravasation into the abdominal cavity. The mean follow-up period was 6 mo, with no lesion residue or recurrence noted. EFR is efficacious, safe and minimally invasive for patients with gastric SMTs arising from the muscularis propria layer. This technique is able to resect deep gastric lesions while providing precise pathological information about the lesion. With the development of EFR, the indications of endoscopic resection might be extended.

    Gallbladder emptying and filling was studied in eight diabetic and six normal control patients. None of the patients had gallstones. Cholescintigraphy was performed using [/sup 99m/Tc]disofenin, and gallbladder emptying was studied using a 45-min i.v. infusion of the octapeptide of cholecystokinin (OP-CCK) 20 ng/kg X hr. The peak filling rate was greater in diabetic than in normal subjects; however, emptying of the gallbladder in response to OP-CCK was significantly less in the diabetic subjects (51.6 +/- 10.4% compared with 77.2 +/- 4.9%). When the diabetic group was subdivided into obese and nonobese diabetics, the obese diabetics had a much lower percentage of emptying than the nonobese diabetics (30.0 +/- 10.4% compared with 73.1 +/- 9.3%). These findings suggest that obese diabetics may have impaired emptying of the gallbladder even in the absence of gallstones. The more rapid rate of gallbladder filling in obesity may indicate hypotonicity of the gallbladder. The combination of these abnormalities may predispose the obese diabetic to the development of gallstones

    The prognosis of gallbladder cancer is basically dependent on the histological stage at diagnosis. In practice, the discovery of a small cancer of the bladder, generally during cholecystectomy give the patient a better care for curative treatment. The advent of laparoscopy has increased the number of cholecstectomies and could increase the frequency of this situation but also raises the difficult problem of metastatic dissemination. In the literature the figures on parietal metastasis after laparoscopy have ranged from 125% to 19%. The median delay to diagnosis of recurrence is 6 months. The cause of this phenomenon (role of the pneumoperitoneum) remains poorly elucidated. Risk factors for the development of a metastasis on the trocar orifice are: rupture of the gallbladder perioperatively and extraction of the gallbladder without protection. It is important to keep in mind this exceptional but serious risk and apply rigorous operative technique. In case of suspected gallbladder we do not advocate laparoscopy. Surgery (hepatectomy, lymphodenectomy, possibly resection of the biliary tract) would be indicted for all stages except pTis and T1a, taking into consideration the localization of the tumor and the patient's general status. It is also classical to recommend resection of the trocar orifices after laparoscopic cholecystectomy. There is a dual challenge today for small-sized gallbladder cancer: improving treatment and avoiding poorer prognosis due to the specific problems raised by laparoscopy.

    Congenital agenesis of the gallbladder is a rare anomaly which is usually asymptomatic and found incidentally. In some cases, however, patients are symptomatic. Common symptoms include right upper quadrant abdominal pain, nausea, and vomiting. Jaundice is present in some symptomatic cases and is due to associated choledocholithiasis (Fiaschetti et al. 2009). In this case, a 63-year-old female presents with jaundice and episodic right upper quadrant abdominal pain with nausea and vomiting. Bilirubin and alkaline phosphatase were found to be markedly elevated. Upper endoscopic ultrasound (EUS) revealed choledocholithiasis, and the patient required multiple endoscopic retrograde cholangiopancreatography (ERCP) sessions before successful extraction of all stones. Subsequent surgical exploration revealed congenital agenesis of the gallbladder. Although this is a rare finding, patients with agenesis of the gallbladder are at increased risk of developing de novo choledocholithiasis which may be challenging to extract.

    A 4-year-old neutered male Chihuahua was presented with a history of anorexia and vomiting. Continuous elevation of liver enzymes was found on repeated blood examinations and the dog was referred to us for further evaluation. The absence of gallbladder was suspected on ultrasonography. Exploratory laparotomy and retrograde cholangiography confirmed gallbladder agenesis and a possible hypoplasia of the right medial and lateral liver lobes. Histologically, proliferation of bile ductules associated with portal fibrosis and pseudolobular formation were apparent in the liver lobes.

    Conclusions: Percutaneous abscesses arising from the gallbladder are a rare but potentially serious consequence of acute cholecystitis, and may present in a wide variety of locations. Therefore it is imperative to conduct a full body inspection in the septic patient, even when a source has been identified.

    The examination of stromal fibrosis within colorectal cancer is overlooked, not only because the routine pathological examinations seem to focus more on tumour staging and precise surgical margins, but also because of the lack of efficient diagnostic methods. Multiphoton microscopy (MPM) can be used to study the muscularis stroma of normal and colorectal carcinoma tissue at the molecular level. In this work, we attempt to show the feasibility of MPM for discerning the microstructure of the normal human rectal muscle layer and fibrosis colorectal carcinoma tissue practicably. Three types of muscularis propria stromal fibrosis beneath the colorectal cancer infiltration were first observed through the MPM imaging system by providing intercellular microstructural details in fresh, unstained tissue samples. Our approach also presents the capability of quantifying the extent of stromal fibrosis from both amount and orientation of collagen, which may further characterize the severity of fibrosis. By comparing with the pathology analysis, these results show that the MPM has potential advantages in becoming a histological tool for detecting the stromal fibrosis and collecting prognosis evidence, which may guide subsequent therapy procedures for patients into good prognosis.

    Abstract Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered. If accumulated fluids contain bile, endoscopic cholangiography is useful not only to diagnose gallbladder injury but also to determine the therapeutic strategy. PMID:27462188

    It is well known that realtime ultrasonography is the primary diagnostic modality to evaluate gallbladder diseases. The authors studied ultrasonographic findings of 10 pathologically proven gallbladder carcinoma patients, and it was compared with the findings of 4 cases of ERCP and 2 cases of CT which were performed at the same period. The results were as follows: 1. They were 6 males and 4 females with over 50 years of age except a 41 year old female. 2. The ultrasonographic classifications of the cases were 4 of fungating mass types, 3 of mass filling gallbladder types, 2 wall thickening types and 1 of mixed type, wall thickening and fungating mass. 3. Seven cases of cholecystitis, 6 cases of intrahepatic biliary duct dilatation, 5 cases of gallstone, 4 cases of common bile duct dilatation, 4 cases of sludge bile, 2 cases of gallbladder dilatation, 1 case of right sub phrenic and pericholecystic abscess due to perforated gallbladder. 4. Five cases of mesenteric infiltrations, 3 cases of hepatic infiltration adjacent to gallbladder, 2 cases of lymphatic metastasis to right lobe of liver and 2 cases of pericholedochal and pericaval lymph node metastasis. 5. The indistinct margin between gallbladder and surrounding organ adjacent to gallbladder mass or gallbladder wall thickening suggest cancer infiltration to adjacent organ such as liver or omentum. 6. If gallstone is engulfed in thickened gallbladder wall, the wall thickening suggests gallbladder carcinoma. 7. The differentiation between fungating mass and sludge bile, and the determination of mass could be done by positional change. 8. The preoperative ultrasonic diagnositc accuracy was in 9 out of 10 cases (90%). 9. Because of the frequent cystic duct obstruction by associated inflammation, the diagnostic accuracy of ERCP for gallbladder carcinoma was low.

    Full Text Available We encountered a case of gallbladder volvulus in an 88-year-old thin female in which the initial presentation was more consistent with that of acute appendicitis. After complete work-up, including physical exam, lab work, and computed tomography, the definite diagnosis of gallbladder volvulus was not made until intraoperative visualization was obtained. Gallbladder volvulus is a rare but serious condition, which requires a high clinical suspicion so prompt surgical intervention can be undertaken.

    Carcinoma of the gallbladder is a relatively rare malignancy which is difficult to diagnose. The advent of improved imaging methods and the expansion of interventional radiology however, combined with advances in surgical technique, has produced a change in attitude towards this tumour. The available world literature since 1960 has been reviewed and is presented in this article. However, whilst the outlook for diagnosis and treatment is improving, clearly the association with cholelithiasis (...

    Most cases of colorectal cancer develop via an adenoma to carcinoma sequence. Gallbladder polyps share some risk factors with colorectal polyps. Little is known about the relationship between gallbladder diseases and different status of colorectal polyps by gender. This study was to investigate the association of gallbladder stones and polyps with colorectal adenomas by gender in a Taiwanese population. A total of 7066 eligible subjects who underwent a total colonoscopy as a part of health check-up between January 2001 and August 2009 were recruited. Colonoscopic findings were classified into polyp-free, non-neoplastic polyps and colorectal adenomas. Gallbladder stones and gallbladder polyps were diagnosed based on ultrasonographic findings. There was a significant difference in the status of colon polyps between subjects with and without gallbladder polyps. However, the status of colon polyps was not significantly different between subjects with or without gallbladder stones. After adjusting obesity, fasting plasma glucose, and other variables, there was a positive relationship between gallbladder polyps and colorectal adenomas (odds ratio [OR]: 1.396, 95% confidence interval [CI]: 1.115-1.747) but not non-neoplastic polyps in all subjects. In men, gallbladder polyps (OR: 1.560, 95% CI: 1.204-2.019) and gallbladder stones (OR: 1.465, 95% CI 1.081-1.984) were positively associated with colorectal adenomas. In women, neither gallbladder polyps nor gallbladder stones were significantly related to colon polyps. Both gallbladder polyps and gallbladder stones were associated with an increased risk of colorectal adenomas in men but not in women. Gender difference was significant for the association between gallbladder lesions and colorectal polyps. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    In recent years, some Chinese doctors have proposed a new concept, gallstone removal without gallbladder excision, along with transition of the medical model. As there is no specialized endoscope for gallstone removal without gallbladder excision, we designed and produced a new series of gallbladder endoscopes and accessories that have already been given a Chinese invention patent (No. ZL200810199041.2). The design of these gallbladder endoscopes was based on the anatomy and physiology of the gallbladder, characteristics of gallbladder disease, ergonomics, and industrial design. This series of gallbladder endoscopes underwent clinical trials in two hospitals appointed by the State Administration of Traditional Chinese Medicine. The clinical trials showed that surgeries of gallstones, gallbladder polyps, and cystic duct calculus could be smoothly performed with these products. In summary, this series of gallbladder endoscopes is safe, reliable, and effective for gallstone removal without gallbladder excision. This note comprehensively introduces the research and design of this series of gallbladder endoscopes.

  6. The role of the gallbladder in humans

    Directory of Open Access Journals (Sweden)

    J.L. Turumin

    2013-07-01

    Full Text Available The basic function of the gallbladder in humans is one of protection. The accumulation of the primary bile acids (cholic acid and chenodeoxycholic acid in the gallbladder reduces the formation of the secondary bile acids (deoxycholic acid and lithocholic acid, thus diminishing their concentration in the so-called gallbladder-independent enterohepatic circulation and protecting the liver, the stomach mucosa, the gallbladder, and the colon from their toxic hydrophobic effects. The presence or absence of the gallbladder in mammals is a determining factor in the synthesis of hydrophobic or hydrophilic bile acids. Because the gallbladder contracts 5-20 min after food is in the stomach and the “gastric chyme” moves from the stomach to the duodenum 1-3 h later, the function of the gallbladder bile in digestion may be insignificant. The aim of this article was to provide a detailed review of the role of the gallbladder and the mechanisms related to bile formation in humans.

    1975-05-01

    The gallbladder B-scans of 20 patients who had subsequent surgery were separated into three categories based upon certain sonographic criteria. Our data, in this limited series, revealed gallbladder pathology in each patient who had any one or combination of the following scan characteristics: (1) internal echos, (2) irregular wall, or (3) absence of recognizable gallbladder sonolucency. The category which demonstrated a normal sonographic gallbladder, namely a smooth wall and no internal echos, contained a number of false negatives which proved to have either small stone cholelithiasis or extraphepatic ductal obstruction. Within the described limitations, the B-scan can be a valuable test in confirming the significance of a radiographically nonvisualized gallbladder or in detecting a biliary tract lesion in a patient with a disease entity that precludes radiographic visualization by conventional techniques.

  9. Surgical treatment of gallbladder polypoid lesions

    2003-01-01

    Full Text Available INTRODUCTION Polypoid lesions of the gallbladder can be divided into benign and malignant categories. Malignant polypoid lesions include carcinomas of the gallbladder, which is the fifth most common malignancy of the gastrointestinal tract and the most common malignancy of the biliary tract. Benign polypoid lesions of the gallbladder are divided into true tumors and pseudotumors. Pseudotumors account for most of polypoid lesions of the gallbladder, and include polyps, hyperplasia, and other miscellaneous lesions. Adenomas are the most common benign neoplasms of the gallbladder. Cholesterol polyps are the most common pseudotumors of the gallbladder. The polyps can be single or multiple, usually less than 10 mm in size. They have no predilection for any particular gallbladder site, and usually are attached to the gallbladder wall by a delicate, narrow pedicle. No malignant potential has been identified for this type of pseudotumor. Adenomas are the most common benign neoplasms of the gallbladder. They have no predilection site in the gallbladder, and may also be associated with gallstones or cholecystitis. The premalignant nature of adenomas remains controversial. Ultrasonography (US has been demonstrated to be significantly better in detecting polypoid lesions of the gallbladder as compared with computed tomography and cholecystography. A mass fixed to the gallbladder wall of normal thickness, without shadowing, is seen in case of gallbladder polyp. Since gallbladder cancers usually present as polypoid lesions, differentiation between benign polypoid lesion and malignant lesion can be very difficult, even with high-resolution imaging techniques. PATIENTS AND METHODS Retrospectively we have analyzed 38 patients with ultrasonographicaly detected gallbladder polyps during the period from January 1995 to December 2000, who were treated at surgical department of Health Centre in Uzice and at Surgical clinic of Clinical Centre in Nis. We have analyzed

    Full Text Available Pleomorphic carcinoma is a rare lesion and the literature contains few reports of pleomorphic carcinoma of the gallbladder. The present study reports a rare case of primary pleomorphic carcinoma of the gallbladder for which we were able to perform curative surgery. A 77-year-old woman with dementia developed nausea and anorexia, and computed tomography demonstrated irregular thickening of the gallbladder wall. Drip infusion cholangiography and endoscopic retrograde cholangiopancreatography revealed no stenosis of the common and intrahepatic bile ducts. We suspected carcinoma of the gallbladder without lymph node metastasis and invasion to the common bile duct. We guessed it to be resectable and performed open laparotomy. At operation, the fundus of the gallbladder was adherent to the transverse colon, but no lymph node and distant metastases were detected. Therefore, we performed curative cholecystectomy with partial colectomy. Histopathology and immunostaining showed coexistence of an adenocarcinoma, squamous cell carcinoma and sarcomatous tumor of spindle-shaped cell, as well as transition zones between these tumors. We diagnosed stage I pleomorphic carcinoma of the gallbladder. No recurrence has been observed for one and a half years. The biological behavior of pleomorphic carcinoma of the gallbladder remains unknown. It will be necessary to accumulate more case reports of this tumor in order to define diagnostic criteria.

    2014-01-01

    Abstract Systemic vasculitis (SV) involving abdominal structures usually has a poor prognosis. Gallbladder vasculitis (GV) has been reported as part of SV (GB-SV) and focal single-organ vasculitis (GB-SOV). We analyzed clinical and histologic characteristics of patients with GV to identify features that differentiate GB-SOV from the systemic forms of GV. To identify affected patients with GV we used pathology databases from our institution and an English-language PubMed search. Clinical manifestations, laboratory and histologic features, treatment administered, and outcomes were recorded. Patients were divided in 2 groups, GB-SOV and GB-SV. As in previous studies of single-organ vasculitis, GB-SOV was only considered to be a sustainable diagnosis if disease beyond the gallbladder was not apparent after a follow-up period of at least 6 months. Sixty-one well-characterized patients with GV were included (6 from our institution). There was no significant sex bias (32 female patients, 29 male). Median age was 52 years (range, 18–94 yr). GB-SOV was found in 20 (33%) and GB-SV in 41 (67%) patients. No differences were observed in age, sex frequency, or duration of gallbladder symptoms between groups. Past episodes of recurrent right-upper quadrant or abdominal pain and lithiasic cholecystitis were more frequent in GB-SOV patients, whereas acalculous cholecystitis occurred more often in GB-SV. In GB-SV, gallbladder-related symptoms occurred more often concomitantly with or after the systemic features, but they sometimes appeared before SV was fully developed (13.5%). Constitutional and musculoskeletal symptoms were reported only in GB-SV patients. Compared to GB-SOV, GB-SV patients presented more often with fever (62.5% vs 20%; p = 0.003) and exhibited higher erythrocyte sedimentation rate levels (80 ± 28 vs 37 ± 25 mm/h, respectively; p = 0.006). All GB-SV patients required glucocorticoids and 50% of them also received cytotoxic agents. Mortality in

    Gastrointestinal submucosal tumors (SMTs) have been increasingly identified via the use of endoscopic ultrasonography, and removal is often recommended for SMTs that are >2 cm in diameter or symptomatic. Submucosal tunneling endoscopic resection (STER), also known as submucosal endoscopic tumor resection, endoscopic submucosal tunnel dissection or tunneling endoscopic muscularis dissection, is a novel endoscopic technique for treating gastrointestinal SMTs originating from the muscularis propria layer, and has been demonstrated to be effective in the removal of SMTs with a decreased rate of recurrence by clinical studies. STER may be performed for patients with esophageal or cardia SMTs, and its application has expanded beyond these types of SMTs due to modifications to the technique. The present study reviewed the applications, procedure, efficacy and complications associated with STER.

    Full Text Available Isolated mycobacterial infection of gall bladder is an extremely rare entity. Only anecdotal reports are evident in the literature. A preoperative diagnosis of mycobacterial infection of gallbladder is therefore very difficult. The case of a 72-year-old male who underwent surgery for suspected gallbladder cancer is presented. The diagnosis of cancer was based on radiological findings and an abnormal uptake of fluorine-18-fluoro-2-deoxy-D-glucose (FDG on positron emission tomography (PET scan whilst being followed up for colorectal cancer. He underwent cholecystectomy and gallbladder bed resection. Histopathology was consistent with mycobacterial infection of the gallbladder.

    Tuberculosis (TB) is an infectious disease that can affect any organ system of the body. Abdominal TB can be gastrointestinal, lymph nodal, visceral or peritoneal. The gallbladder (GB) is rarely involved in abdominal TB as a primary organ. Extensive research literature on gallbladder TB is limited to case reports. There has been no review on this rare abdominal pathology. GB tuberculosis is a difficult diagnosis preoperatively. It is a rare differential among the more common gallbladder pathologies such as cholelithiasis, or a gallbladder malignancy. Typical histopathology of the resected specimen helps to establish this rare diagnosis. Subjecting every specimen to histopathological examination followed by medical treatment offers the chance of cure. Through this review, the authors attempt to provide an insight into this disease entity.

    Adenocarcinoma of the gallbladder developed in 17 of 68 untreated and in 26 of 83 irradiated guinea pigs of inbred strains 2 and 13. The carcinomas spread widely by direct extension and through lymphatic and blood vessels to lymph nodes, mesenteries, omenta, abdominal wall, liver, lungs, bones, and spleen. Whole-body exposure to gamma or x radiation increased both the number of tumors and metastases in male inbred guinea pigs but not in females. Significantly fewer (9 of 98) noninbred than inbred guinea pigs developed gallbladder carcinomas after irradiation. In 9 untreated noninbred guinea pigs gallbladder carcinomas were not found. Inasmuch as the effect of irradiation was not dose-dependent, an indirect systemic effect of irradiation was postulated. This is the first report on the occurrence of spontaneous gallbladder adenocarcinomas in guinea pigs

    There is an extensive menu for investigating the hepatobiliary area. From the simplicity of the plain film to the expense of magnetic resonance imaging to the invasiveness of percutaneous transhepatic cholangiography, all modalities can contribute to the goal of a correct diagnosis. Not all are needed in each patient; thus a careful evaluation of the clinical needs is required before proceeding. It is also apparent that changes are occurring rapidly. The current importance of gallbladder ultrasonography and computerized tomography and the decline of oral cholecystography and intravenous cholangiography in biliary tract diagnosis was impossible to anticipate a decade ago. Because not all modalities are available in all communities, it is important to tailor the diagnostic algorithm to local skills and equipment

    Fifty patients with cholesterol stones in their gallbladder, with few symptoms were treated with the bile acids cheno- or ursodeoxycholic acid. 38 had a 'normal' gallbladder, 12 had diverticula of the gallbladder. After the complete dissolution of the stones the bile acid treatment was stopped. The follow-up period lasted up to 7 years. No recurrence was observed in the gallbladder of 18 patients, but 32 developed new stones. With a second bile acid treatment we could dissolve the new stones of 13 patients, up to now without further relapses. After the second bile acid treatment of 9 months and x-ray controls 19 patients (38%) developed insoluble material in their gallbladders, independent of the presence of diverticula. We tried to eliminate calcium sediments with cholecystokinin-like substances. Temporary success was achieved in three of five patients only, and one person only remained free of further relapses. There is no reason to exclude patients with cholesterol stones and diverticula of the gallbladder from litholytic therapy. 10 figs.

After the complete dissolution of the stones the bile acid treatment was stopped. The follow-up period lasted up to 7 years. No recurrence was observed in the gallbladder of 18 patients, but 32 developed new stones. With a second bile acid treatment we could dissolve the new stones of 13 patients, up to now without further relapses. After the second bile acid treatment of 9 months and x-ray controls 19 patients (38%) developed insoluble material in their gallbladders, independent of the presence of diverticula. We tried to eliminate calcium sediments with cholecystokinin-like substances. Temporary success was achieved in three of five patients only, and one person only remained free of further relapses. There is no reason to exclude patients with cholesterol stones and diverticula of the gallbladder from litholytic therapy. (orig.) [de

    The thickening of the gallbladder wall is a valuable finding for the diagnosis of cholecystitis, but may be seen in non-cholecystic disease as well as in acute or chronic cholecystitis. The purpose of this study is to determine the value of color Doppler sonography in differentiating the causes of thickened gallbladder wall. Ninety eight patients with thickened gallbladder wall(more than 3mm) which was not due to gallbladder cancer were prospectively evaluated with color Doppler sonography. Sixty-six cases, confirmed by pathologic reports and clinical records, were analyzed for correlation between thickened gallbladder wall and color flow signal according to the underlying causes. Of the 66 patients, 28 cases were cholecystitis and 38 cases had non-cholecystic causes such as liver cirrhosis, ascites, hepatitis, pancreatitis, renal failure, and hypoalbuminemia. Of the 28 patients with cholecystitis(12 acute, 16 chronic), 23(82%) had color Doppler flow signals in the thickened gallbladder wall. Of the 38 patients with non-cholecystic causes, eight(21%) had color Doppler flow signals. There was a statistically significant difference of color Doppler flow signals between the cholecystitis and non-cholecystic groups(p=0.0001). No significant difference of color Doppler flow signals was found between cases of acute and chronic cholecystitis. Of the 23 patients with color Doppler flow signals in 28 cases of cholecystitis, 18(78.3%) showed a linear pattern and five(21.7%) showed a spotty pattern. Of the eight patients with color Doppler flow signals in the 38 non-cholecystic cases, four(50%) showed a linear pattern and four(50%) showed a spotty pattern. In cholecystitis, a linear color Doppler flow signal pattern is a much more frequent finding than a spotty pattern. Color Doppler sonography is a useful and adequate method for determining whether a thickened gallbladder wall is the result of cholecystitis or has non-cholecystic causes

    Full Text Available Abstract Introduction Torsion of the gallbladder is a rare condition that most commonly affects the elderly. Pre-operative diagnosis is the exception rather than the rule. Any delay in treatment can be fatal as the gallbladder may rupture, leading to biliary peritonitis. Case presentation We present the case of an 80-year-old woman who was admitted with right upper quadrant pain initially thought to be secondary to acute cholecystitis. Subsequent ultrasound and computed tomography scans of the abdomen revealed signs suggestive of acute cholecystitis but neither modality detected any gallstones. As the patient's symptoms failed to resolve on conservative management, she was taken to theatre for an open cholecystectomy. Intra-operatively, the gallbladder had undergone complete torsion and appeared gangrenous. A routine cholecystectomy followed and she recovered from the operation without incident. Conclusion It is rare to diagnose torsion of the gallbladder pre-operatively despite advances in diagnostic imaging. However, this differential diagnosis should be borne in mind particularly in the elderly patient, without proven gallstones, who fails to improve on conservative management. An emergency cholecystectomy is indicated in the event of diagnosing torsion of the gallbladder to avert the potentially lethal sequelae of biliary peritonitis.

    Large differences in terms of incidence and mortality due to gallbladder cancer (GBC) have been reported worldwide. Moreover, it seems that GBC has unique characteristics in South America. We surveyed the literature looking for information about the epidemiology, basic and translational research, and clinical trials performed in South America in order to critically analyze the magnitude of this health problem in the region. Compared to other geographic areas, age-standardized mortality rates (ASMR) for GBC in women are very high, particularly in many western areas of South America. Genetic, as well as dietary and environmental factors likely contribute to the pathogenesis of this disease in the area. Compared to other regions the profile of abnormalities of key genes such as KRAS and TP53 in GBC seems to slightly differ in South America, while the clinical behavior appears to be similar with a median overall survival (OS) of 6.5 to 8 months in advanced GBC. In contrast to Europe and USA, prophylactic cholecystectomy is a common practice in western areas of South America. GBC particularly affects women in South America, and represents a significant public health problem. It appears to have peculiarities that pose an urgent need for additional research aimed to discover risk factors, molecular events associated with its development and new treatment options for this lethal disease.

    OBJECTIVE To examine bile acid composition of gallbladder contents in dogs with gallbladder mucocele and biliary sludge. ANIMALS 18 dogs with gallbladder mucocele (GBM group), 8 dogs with immobile biliary sludge (i-BS group), 17 dogs with mobile biliary sludge (m-BS group), and 14 healthy dogs (control group). PROCEDURES Samples of gallbladder contents were obtained by use of percutaneous ultrasound-guided cholecystocentesis or during cholecystectomy or necropsy. Concentrations of 15 bile acids were determined by use of highperformance liquid chromatography, and a bile acid compositional ratio was calculated for each group. RESULTS Concentrations of most bile acids in the GBM group were significantly lower than those in the control and m-BS groups. Compositional ratio of taurodeoxycholic acid, which is 1 of 3 major bile acids in dogs, was significantly lower in the GBM and i-BS groups, compared with ratios for the control and m-BS groups. The compositional ratio of taurocholic acid was significantly higher and that of taurochenodeoxycholic acid significantly lower in the i-BS group than in the control group. CONCLUSIONS AND CLINICAL RELEVANCE In this study, concentrations and fractions of bile acids in gallbladder contents were significantly different in dogs with gallbladder mucocele or immobile biliary sludge, compared with results for healthy control dogs. Studies are needed to determine whether changes in bile acid composition are primary or secondary events of gallbladder abnormalities.

    Full Text Available Parastomal gallbladder herniation is a rare complication of enterostomies with only 6 previously reported cases. Most cases have occurred in elderly women. Patients typically presented with acute abdominal pain and the majority was managed operatively. Here, we report the clinical course of an 88-year-old female who presented with signs of sepsis and minimal abdominal symptoms. She was subsequently found to have a parastomal gallbladder herniation and Klebsiella pneumoniae bacteremia. Given the patient's multiple comorbidities, she was managed nonoperatively with manual reduction of the parastomal hernia and antibiotics.

    Real-time ultrasonography is a simple, accurate, noninvasive and potentially valuable means of studying gallbladder size and emptying. The authors calculated ultrasonographically the ejection fraction of 80 cases of normally functioning gallbladder on oral cholecystography, from June 1983 to April 1984, at the department of radiology, Hangang Sacred Heart Hospital. The results were obtained as follows; 1. Ultrasonographic Ejection Fraction at 30 minutes after the fatty meal was 73.1{+-}16.85. 2. There was no significant difference in age and sex, statistically.

  11. Gallbladder Boundary Segmentation from Ultrasound Images Using Active Contour Model

    Science.gov (United States)

    Ciecholewski, Marcin

    Extracting the shape of the gallbladder from an ultrasonography (US) image allows superfluous information which is immaterial in the diagnostic process to be eliminated. In this project an active contour model was used to extract the shape of the gallbladder, both for cases free of lesions, and for those showing specific disease units, namely: lithiasis, polyps and changes in the shape of the organ, such as folds or turns of the gallbladder. The approximate shape of the gallbladder was found by applying the motion equation model. The tests conducted have shown that for the 220 US images of the gallbladder, the area error rate (AER) amounted to 18.15%.

    Gallbladder cancer is common in north India. It is also a well established fact that gall bladder cancer is frequently associated with gallstone disease in north India, similar to reports from the West. The magnitude of the problem of gallbladder cancer in south India and its link to gallstone disease is not clearly established. The aim of the study was to determine retrospectively, the characteristics of individuals with GBC in south India and to determine its association with gallstone disease. Retrospective data was obtained from records of proven cases of gallbladder cancer and patients undergoing cholecystectomy for gallstone disease between Jan 2001 and Dec 2010. Data retrieved included age, gender, and clinical presentation, findings on imaging, histology and details of management. The number of proven cases of gallbladder cancer each year ranged from 8 to 17. There were 38 men and 23 women. Male female ratio was 1.6:1. There were more men in the successive decades. Right upper quadrant pain (42 %) followed by jaundice (27 %) and a presence of a palpable mass (12 %) were the common clinical presentation. Pre-operative diagnosis of gall bladder cancer was possible in 80 %. Twelve patients had co-existing gallstones (19.6 %). Forty patients (50 %) had stage IV disease; only 6 patients had Stage I operable disease (9.8 %). During the same time 758 patients had cholecystectomy for gallstone disease. Only one patient had an incidental gall bladder cancer, who had an extended cholecystectomy. Gallbladder cancer is uncommon in south India and its association with gallstone is also low.

    Gallbladder stones are a very frequently occurring condition. Despite bile bactericidal activity, many bacteria have been detected inside the gallbladder, and gallstones facilitate their presence. Between 3% and 5% of the patients with Salmonella spp. infection develop the carrier stage, with the bacteria persisting inside the gallbladder, shedding bacteria in their feces without signs of infection. The aim of this study was to isolate bacteria from Colombian patients with gallstones, using standard culturing methods, and to identify Salmonella spp. carriers by molecular techniques. A total of 149 patients (120 female and 29 male) diagnosed with gallstones who underwent cholecystectomy and who did not have symptoms of acute inflammation were included. Gallbladder tissue and bile were cultured and used for DNA extraction and Salmonella spp. hilA gene detection. Of the 149 patients 28 (19%) had positive cultures. Twenty-one (75%) patients with positive cultures were from Medellin's metropolitan area. In this geographical location, the most frequent isolations were Pseudomonas spp. (38%), Klebsiella spp. (23%), and Proteus spp. (9%) in addition to unique cases of other bacteria. In Apartado, the isolates found were Enterobacter cloacae (50%), Raoultella terrigena (32%), and both Enterobacter cloacae and Raoultella terrigena were isolated in one (18%) male patient. Five (3.3%) of the 149 patients had positive polymerase chain reaction (PCR) results for the hilA gene of Salmonella spp., all of whom were female and residents of the Medellín metropolitan area. The gallbladder microbiota variability found could be related to geographical, ethnic, and environmental conditions.

    Full Text Available Abstract Background Carcinoma of the gallbladder (GBC clinically mimics benign gallbladder diseases and often escapes detection until advanced stage. Despite the frequency of cholecystectomy, diagnosis of GBC remains problematic in many situations. We sought to identify pathologic features that contribute to the difficulty in recognition of GBC. Methods We identified 23 patients (ranged from 45 to 86 years, male to female ratio 1:4.5 with carcinoma involving the gallbladder referred to an academic medical center over a period of 10 years for study. This includes 10 cases of primary GBC, 6 cases of metastatic tumor to gallbladder, 6 cases of directly invasive adenocarcinoma arising elsewhere in the biliary tree, and one case of unidentified origin adenocarcinoma. Primary tumors include adenocarcinoma not otherwise specified (NOS in 6 cases, papillary adenocarcinoma in 2 cases, and single cases of undifferentiated carcinoma and combined adenocarcinoma and neuroendocrine carcinoma (NEC. Metastatic tumors to gallbladder were from a wide range of primary sites, predominantly the gastrointestinal tract. Results These cases illustrate seven potential pitfalls which can be encountered. These include: 1 mistakenly making a diagnosis of adenocarcinoma of gallbladder when only benign lesions such as deeply penetrating Rokitansky-Aschoff sinuses are present (overdiagnosis, 2 misdiagnosing well-differentiated invasive carcinoma with minimal disease as benign disease (underdiagnosis, 3 differentiating between primary NEC of gallbladder and metastasis, 4 confusing primary mucinous adenocarcinoma of gallbladder with pseudomyxoma peritonei from a low grade appendiceal neoplasm disseminated to gallbladder, 5 confusing gangrenous necrosis related to cholecystitis with geographic tumoral necrosis, 6 undersampling early, grossly occult disease, and 7 misinterpreting extracellular mucin pools. Conclusions Clinical history and a high index of suspicion are

    Spontaneous cholecystocutaneous fistula (SCF) is a rare complication of neglected calculous biliary disease and also an extremely rare complication of gallbladder neoplasm. This pathology has become even rarer because of prompt diagnosis and expedient surgical intervention for gallstones. So far, there is one published report of a SCF due to gallbladder adenocarcinoma. We present the case of a woman aged 87 years, admitted to the Vth Department of Surgery, Clinical Municipal Hospital of Cluj-Napoca (Romania) for a tumoral mass located in the epigastrium. In the epigastrium, the patient had three skin orifices of about 1-2 mm each, through which purulent secretion occurred. The abdominal ultrasound highlighted a cholecystocutaneous fistula with the presence of a subcutaneous gallstone. Intraoperatively, we found a cholecystocutaneous fistula, a 1 cm subcutaneous gallstone, gallbladder with thickened walls containing a cylinder-shaped gallstone of 5÷3 cm. Fistulectomy, gallstones extraction and cholecystectomy were performed. The histopathological examination highlighted gallbladder adenocarcinoma. In conclusion, SCF can be the first significant manifestation of gallbladder cancer associated with neglected calculous biliary disease.

    Fifteen patients underwent CT examination shortly after abdominal angiography with iodixanol. Gallbladder opacification was observed in 13 patients in the absence of clinical evidence of renal impairment. Among them, 2 patients showed a strong opacification on CT. There was no significant relationship between visualization of the gallbladder and the total dose of contrast medium. Gallbladder opacification on CT examination shortly after angiography shows that the hepatobiliary tract is important in the excretion of iodixanol. (author)

    The diagnosis of blunt injury to the gallbladder may constitute a significant challenge to the diagnostician. There is often a delay in presentation with non-specific clinical symptoms. In the absence of reliable clinical symptoms, diagnostic imaging becomes an invaluable tool in the rapid identification of gallbladder injury. We present a case of isolated gallbladder injury following blunt abdominal trauma which was diagnosed by computed tomography and subsequently confirmed by cholecystectomy.

    Chile has the world's highest rate of incidence as well as death from cancer of the gallbladder and biliary ducts. The problem is most acute in the southern provinces. These areas constitute the low average income associated with low educational attainment and a high rate of obesity compared with the rest of Chile. We could also include genetic factors related to processes of lithogenesis to these elements which are more common among the Mapuche. This population sub-group could benefit from special government programmes for early diagnosis and treatment of lithiasic disease and for the management of risk factors such as obesity. In this way, we could reduce the mortality rate of gallbladder cancer.

    Many studies have reported methods of cell collection involving percutaneous transhepatic cholangiodrainage (PTCD) and fine-needle aspiration cytology for the diagnosis of gallbladder disease. However, few studies have described the use of a transpapillary approach, i.e., endoscopic transpapillary catheterization into the gallbladder (ETCG). In this study, we analyzed cells collected by ETCG to evaluate its usefulness in the cytological diagnosis of gallbladder disease. The subjects were 19 patients who had undergone ETCG for the diagnosis of gallbladder disease. Of these patients, 11 and 8 had gallbladder cancer and benign gallbladder disease, respectively. We also evaluated the diagnostic accuracy of PTCD cytology performed in 15 patients with gallbladder cancer.Specimens were cytologically diagnosed as normal or benign, indeterminate, suspected malignancy, malignant, and inadequate in 47% (9/19), 11% (2/19), 0% (0/19), 37% (7/19), and 5% (1/19) of patients, respectively. Specimens were diagnosed as malignant, indeterminate, normal or benign, and inadequate in 7, 2, 1, and 1, respectively, of the 11 patients diagnosed with gallbladder cancer. The sensitivity and specificity of ETCG cytology were 78 and 100%, respectively, whereas the diagnostic accuracy of PTCD cytology was 20% (3/15). None of the patients developed complications of ETCG. Despite its technical difficulty, ETCG for bile cytology allows the collection of adequate cell numbers from patients with benign disease or gallbladder cancer and facilitates a cytological diagnosis, making it a useful method for collecting cells.

    Objective: To evaluate CT findings of liver and gallbladder in type II diabetics and to discuss diabetic, and investigate the correlation between type II diabetics, and investigate the correlation between the diabetes and the lesions found in the liver or gallbladder. Methods: Retrospective analysis was made on the CT findings of hepatic and gallbladder lesions in 586 cases of II diabetes. Results: In total 586 type II diabetics, cholecystitis and/or gallstone were revealed in 33.45% patients; and hepatic alteration was noted in 20.48% cases. Hepatic abnormalities were found in 58.67% cases in the cholecystitis/gallstone group, significantly different from the group with unremarkable gallbladder, in which hepatic lesions were found only in 1.28% cases. Conclusion: The hepatic alteration is secondary to the gallbladder lesions in type II diabetics. (authors)

    OBJCTIVE To investigate the effects of dietary lipid overload on bile acid metabolism and gallbladder motility in healthy dogs. ANIMALS 7 healthy Beagles. PROCEDURES In a crossover study, dogs were fed a high-fat-high-cholesterol diet (HFCD) or a low-fat diet (LFD) for a period of 2 weeks. After a 4-month washout period, dogs were fed the other diet for 2 weeks. Before and at the end of each feeding period, the concentrations of each of the gallbladder bile acids, cholecystokinin (CCK)-induced gallbladder motility, and bile acid metabolism-related hepatic gene expression were examined in all dogs. RESULTS The HFCD significantly increased plasma total cholesterol concentrations. The HFCD also increased the concentration of taurochenodeoxycholic acid and decreased the concentration of taurocholic acid in bile and reduced gallbladder contractility, whereas the LFD significantly decreased the concentration of taurodeoxycholic acid in bile. Gene expression analysis revealed significant elevation of cholesterol 7α-hydroxylase mRNA expression after feeding the HFCD for 2 weeks, but the expression of other genes was unchanged. CONCLUSIONS AND CLINICAL RELEVANCE Feeding the HFCD and LFD for 2 weeks induced changes in gallbladder bile acid composition and gallbladder motility in dogs. In particular, feeding the HFCD caused an increase in plasma total cholesterol concentration, an increase of hydrophobic bile acid concentration in bile, and a decrease in gallbladder sensitivity to CCK. These results suggested that similar bile acid compositional changes and gallbladder hypomotility might be evident in dogs with hyperlipidemia.

The mass proved to be a gallbladder incarcerated in a hernia of the umbilical cord. Distinguishing an omphalocele from an umbilical cord hernia is not obvious and can be arbitrary. Morphologically, the two terms both describe congenital abdominal wall defects covered by a membrane, typically containing abdominal organs.

    A 69 years old woman was admitted under the case of physicians with lethargy and anemia. While in-hospital, she developed severe pain in the right hypochondrium with vomiting. Past medical history included peripheral vascular disease, appendicectomy and tuberculous meningitis. On examination, she had tachycardia, hypotension was pale, apyrexic, clinically anicteric and markedly tender over right upper quadrant with mild guarding. Her hemoglobin was 8.5 gm/dl, white cell count was 25,000 per L and had a raised C Reactive Protein of 110. Her liver functions were normal. Plain abdominal radiograph revealed dilated small bowel in the upper abdomen. Provisional diagnosis of acute cholecystitis was made and conservative management was started initially, using intravenous cefuroxime. She deteriorated rapidly, developed metabolic acidosis and atrial fibrillation. CT scan did not reveal a significant abnormality. There were no gallstones and no evidence of acute cholecystitis. An emergency laparotomy revealed a gangrenous gallbladder and twisted more than 3600 anticlockwise on its pedicle. Cholecystectomy was performed and she was managed in intensive care unit. She developed abdominal compartment syndrome requiring re-exploration and a laparostomy. On the fifth post-op day her abdomen was successfully closed with a mesh. Despite intensive monitoring and vigorous management, she developed multi-organ failure and died five weeks after her first operation. Histology confirmed venous infarction of an acalculous gallbladder without cholelithiasis. (author)

    Full Text Available Objective. Contractility of gallbladder is known to be decreased in fatty gallbladder diseases. However, clinical estimation data about this relationship is still lacking. The aim of this study was to investigate the association between steatocholecystitis and contractility of gallbladder. Methods. Patients with cholecystitis (steatocholecystitis versus nonsteatocholecystitis who underwent cholescintigraphy before cholecystectomy were retrospectively evaluated in a single teaching hospital of Korea. The association of steatocholecystitis with contractility of gallbladder, measured by preoperative cholescintigraphy, was assessed by univariable and multivariable analysis. Results. A total of 432 patients were finally enrolled (steatocholecystitis versus nonsteatocholecystitis; 75 versus 357, calculous versus acalculous cholecystitis; 316 versus 116. In the multivariable analysis, age (OR: 0.94, 95% CI: 0.90–0.99, P=0.01 and total serum cholesterol (OR: 1.02, 95% CI: 1.01–1.04, P=0.04 were related to steatocholecystitis in patients with acalculous cholecystitis. Only age (OR: 0.97, 95% CI: 0.94–0.99, P=0.004 was significantly related to steatocholecystitis in patients with calculous cholecystitis. However, ejection fraction of gallbladder reflecting contractility measured by cholescintigraphy was not related to steatocholecystitis irrespective of presence of gallbladder stone in patients with cholecystitis. Conclusion. Ejection fraction of gallbladder measured by cholescintigraphy cannot be used for the detection or confirmation of steatocholecystitis.

    To study the magnetic resonance imaging (MRI) appearance of the fetal gallbladder with special reference to fetal gallbladder sludge. In a retrospective study of 512 fetuses without gastrointestinal abnormalities, we classified the gallbladder MR appearances into patterns based on the signal intensity (SI) of bile on T1-weighted and T2-weighted sequences. We analysed the ratio of T1-weighted SI of bile. Maximum gallbladder width was correlated with gestational weeks (GW) using non-linear regression analysis and compared between various imaging patterns with one-way ANOVA. Five age-dependent patterns of the MRI appearance were found: (1) SI of bile was T2-weighted hyperintense and T1-weighted hypointense (78.5%); (2) presented with T2-weighted hyperintensity and T1-weighted signal isointense to liver (10.4%); (3) moderate hyperintense T2-weighted SI, T1-weighted SI hyperintense to liver (4.9%); (4) SI was T2-weighted isointense and T1-weighted hyperintense to liver (3.7%); (5) pronounced T2-weighted hypointensity and marked T1-weighted hyperintensity (2.5%). Pattern 1 was exclusively found before 27 GW, while patterns 2-5 increased in frequency after 30 GW. The MRI appearance of the fetal gallbladder is variable; fetal bile shows age-dependent SI changes that may cause non-visualisation of the gallbladder. This may be due to sludge and/or accumulation of paramagnetic substances suspended within gallbladder mucus. (orig.)

  16. Surgical strategies in patients with gallbladder cancer: nihilism to optimism.

    Gallbladder cancer is an aggressive disease with dismal results of surgical treatment and a poor prognosis. However, over the last few decades selected groups have reported improved results with aggressive surgery for gallbladder cancer. Review of recent world literature was done to provide an update on the current concepts of surgical treatment of this disease. Long-term survival is possible in early stage gallbladder carcinoma. Tis and T1a gallbladder carcinoma can be treated with simple cholecystectomy only. However, in T1b and beyond cancers, aggressive surgery (extended cholecystectomy) is important in improving the long-term prognosis. Laparoscopic cholecystectomy should not be performed where there is a high index of suspicion of malignancy due to the frequent association with factors (such as gallbladder perforation and bile spill) which may lead to implantation of cancer cells and dissemination. Surgical resection for advanced carcinoma gallbladder is recommended only if a potentially curative R0 resection is possible. Aggressive surgery with vascular and multivisceral resection has been shown to be feasible albeit with an increase in mortality and morbidity. However, the true benefit of these radical resections is yet to be realized, as the actual number of long-term survivors of advanced gallbladder carcinoma is few. Surgery for gallbladder carcinoma, like other malignancies, has the potential to be curative only in local or regional disease. Pattern of loco-regional spread of disease dictates the surgical procedure. Radical surgery improves survival in early gallbladder carcinoma. The long-term benefit of aggressive surgery for advanced disease is unclear and may be offset by the high mortality and morbidity. Copyright 2006 Wiley-Liss, Inc.

    Gallbladder perforation (GBP) is rare and as a complication of typhoid fever is extremely rare. We present two consecutive patients with GBP diagnosed incidentally at laparotomy. Information on the management of two patients with gallbladder perforation seen at Federal Medical Centre Azare in June and October 2008 was extracted from their case records. The two patients were both males aged 13 years and 16 years. They both presented with high fever of more than 2 weeks duration; and abdominal pain and distension. Both patients had features of generalised peritonitis. Pre-operative diagnoses of typhoid enteric perforation were made based on a positive Widal test. Intra-operative findings however, were that of bile peritonitis and gallbladder perforation. Both had cholecystectomy. Culture of the bile aspirate yielded Salmonella typhi. Gallbladder perforation secondary to typhoid fever should be considered as a differential diagnosis in patients with suspected typhoid enteric perforation in typhoid fever endemic region.

    Gallbladder volvulus in children is rare. Pre-operative diagnosis is considered difficult because of the nonspecific symptoms and inflammatory blood analysis findings. Sometimes diagnosis is confirmed at laparotomy. Many reports mention that the chief complaints of this disease are sudden and severe abdominal pain. We report a case of gallbladder volvulus in a boy with mild clinical symptoms and laboratory data of nonspecific inflammation. A reconstructed coronal CT abdominal view showed clearly the gallbladder torsion. Laparoscopic cholecystectomy was performed and postoperative course was uneventful. Recent reports have suggested the effectiveness of MRI. This case highlights the utility of a reconstructed coronal view of abdominal CT in successful pre-operative diagnosis for gallbladder volvulus in children. (orig.)

    The authors viewed the present status of CT diagnosis in pancreatic and biliary diseases, referring to its future. CT imaged neither normal intrahepatic biliary ducts nor normal pancreatic ducts because of a relatively low resolution. The accuracy of CT in diagnosing obstructive jaundice has been 85 - 100%. CT showed a higher reproducibility than that of ultrasound in follow-up of intrahepatic gallstones. On the other hand, ultrasound was superior to CT in detecting gallstones. Diagnosis of cholecystitis by CT was usually impossible. Detecting early stage of gallbladder cancer by CT is very rarely, but it was of value for investigating the extent of advanced cancers. This tendency was also observed in biliary duct carcinoma, acute and chronic pancreatitis, and carcinoma of the pancreas. Consequently, it was concluded that CT is not appropriate for the purpose of early detection of pancreatic and other cancers. The use of CT with NMR is expected in future. (Ueda, J.)

    Full Text Available Gallbladder cancer (GBC is an uncommon disease in the majority of the world despite being the most common and aggressive malignancy of the biliary tree. Early diagnosis is essential for improved prognosis; however, indolent and nonspecific clinical presentations with a paucity of pathognomonic/predictive radiological features often preclude accurate identification of GBC at an early stage. As such, GBC remains a highly lethal disease, with only 10% of all patients presenting at a stage amenable to surgical resection. Among this select population, continued improvements in survival during the 21st century are attributable to aggressive radical surgery with improved surgical techniques. This paper reviews the current available literature of the 21st century on PubMed and Medline to provide a detailed summary of the epidemiology and risk factors, pathogenesis, clinical presentation, radiology, pathology, management, and prognosis of GBC.

    To describe and evaluate a new cholecystectomy technique combining classical dissection with currently available mini-instrumentation (3 and 5 mm) and gallbladder removal through a short gastrotomy. After a feasibility study, we set up a protocol for this procedure using instrumentation currently available on the market. We performed 106 procedures, including 99 in a prospective study between January 2008 and July 2010. Cholecystectomy was performed with the described technique in 99 of 106 eligible patients (22 males and 77 females, mean age 45.8 years (range 18-77); median BMI 26.4 kg/m2 (range 22-36)). Forty-eight patients had at least one gallstone larger than 10 mm. There were no postoperative gastric complications and recovery was always rapid. This procedure is technically feasible, safe and reproducible. The results are good, with minimal abdominal wall trauma. Normal physical activity can be resumed rapidly with no risk of incisional hernia.

    The results of radiotherapy in 37 patients who were treated for carcinoma of the gallbladder from April 1975 to April 1992 are presented. To analyze the treatment results, patients were divided into four groups depending on treatment modality: intraoperative radiotherapy (IORT) with surgical resection in 9 (resection group), IORT with palliative surgery in 5 (palliative surgery group), hyperthermo-chemo-radiotherapy for inoperable cases in 11 (HCR group), external irradiation for inoperable cases in 12 (ExRT alone group). Most of the patients in the resection group received ExRT. The HCR group showed better local response than the groups treated with palliative surgery and ExRT alone. The mean length of survival in the resection, palliative surgery, HCR and ExRT alone groups was 315 days, 144 days, 246 days and 74 days, respectively. Although no statistically significant difference in survival was observed between the resection and HCR groups, the relapse-free interval of the resection group was significantly longer than that of the other groups. The application of IORT for surgically resectable tumors contributed to improved prognosis and better quality of life. Although IORT for patients with unresectable tumors had little effect on survival, it was considered to play a palliative role in improving the quality of life. The HCR group had a significantly longer survival time and relapse-free interval than the palliative surgery and ExRT alone groups. In conclusion, the application of HCR for inoperable carcinoma of the gallbladder contributed to the improvement of prognosis and quality of life. (author)

    Altered gallbladder motility could predispose to, or result from, gallstone formation and could also explain the alleged relief of biliary colic seen during bile acid therapy. Therefore, in 14 controls, 25 patients with radiolucent gallstones, and 14 patients with radiopaque gallstones, the authors used two techniques to measure gallbladder contraction--radionuclide imaging and real-time ultrasound--in response to one of two stimuli--a Lundh meal or intravenous cholecystokinin-octapeptide. Using the radionuclide technique, postprandial gallbladder emptying (t1/2) was prolonged both in patients with radiopaque and radiolucent gallstones when compared with controls. In patients with radiolucent stones, the t1/2 of gallbladder emptying became further prolonged after 1 mo of therapy with ursodeoxycholic acid. A similar pattern of results was seen after cholecystokinin-octapeptide and also with real-time ultrasound. Thus, after both stimuli and using two independent techniques, gallbladder contraction was reduced in patients with gallstones. The slower and less complete gallbladder emptying with ursotherapy might explain the reduction in biliary colic noted during treatment

  6. Gallbladder shape extraction from ultrasound images using active contour models.

    Gallbladder function is routinely assessed using ultrasonographic (USG) examinations. In clinical practice, doctors very often analyse the gallbladder shape when diagnosing selected disorders, e.g. if there are turns or folds of the gallbladder, so extracting its shape from USG images using supporting software can simplify a diagnosis that is often difficult to make. The paper describes two active contour models: the edge-based model and the region-based model making use of a morphological approach, both designed for extracting the gallbladder shape from USG images. The active contour models were applied to USG images without lesions and to those showing specific disease units, namely, anatomical changes like folds and turns of the gallbladder as well as polyps and gallstones. This paper also presents modifications of the edge-based model, such as the method for removing self-crossings and loops or the method of dampening the inflation force which moves nodes if they approach the edge being determined. The user is also able to add a fragment of the approximated edge beyond which neither active contour model will move if this edge is incomplete in the USG image. The modifications of the edge-based model presented here allow more precise results to be obtained when extracting the shape of the gallbladder from USG images than if the morphological model is used. © 2013 Elsevier Ltd.

    This paper presents an approach to gallbladder shape comparison by using 3D shape modeling and decomposition. The gallbladder models can be used for shape anomaly analysis and model comparison and selection in image guided robotic surgical training, especially for laparoscopic cholecystectomy simulation. The 3D shape of a gallbladder is first represented as a surface model, reconstructed from the contours segmented in CT data by a scheme of propagation based voxel learning and classification. To better extract the shape feature, the surface mesh is further down-sampled by a decimation filter and smoothed by a Taubin algorithm, followed by applying an advancing front algorithm to further enhance the regularity of the mesh. Multi-scale curvatures are then computed on the regularized mesh for the robust saliency landmark localization on the surface. The shape decomposition is proposed based on the saliency landmarks and the concavity, measured by the distance from the surface point to the convex hull. With a given tolerance the 3D shape can be decomposed and represented as 3D ellipsoids, which reveal the shape topology and anomaly of a gallbladder. The features based on the decomposed shape model are proposed for gallbladder shape comparison, which can be used for new model selection. We have collected 19 sets of abdominal CT scan data with gallbladders, some shown in normal shape and some in abnormal shapes. The experiments have shown that the decomposed shapes reveal important topology features.

    Prospective study of gallbladder wall thickness by ultrasonography was performed in 38 patients of acute viral hepatitis and 50 normal subjects as a control group from June 1983 to April 1984. The results were as follows; 1. In normal population, the range of gallbladder wall thickness is from 1 mm to 3 mm with peak incidence in 2 mm (66%, 33 case). Mean thickness of gallbladder wall is about 1.9 {+-} 0.6 mm. 2. In acute viral hepatitis, the range of gallbladder wall thickness is from 2 mm to 8 mm with peak incidence in 3 mm (34%, 13 case), second peak in 4 mm (29%, 11 case). Mean thickness of gallbladder wall is about 3.6 {+-} 1.6 mm, which is thicker than normal with statistical significance. (p<0.005) 3. In acute viral hepatitis, the mean thickness of gallbladder wall is about 4.4 {+-} 1.8 mm in the group of SGOT/SGPT level above 400 IU, and 2.8 {+-} 0.8 mm in the group of SGOT/ SGPT level below 400 IU.

    Full Text Available Introduction. Primary lymphoma of the gallbladder is an extremely rare entity with approximately 50 cases reported so far. In many of these cases the presenting symptoms were mimicking symptomatic gallstone disease and the diagnosis was made postoperatively, especially when the preoperative imaging results were far from suspicious for malignant disease. Patients and Methods. We report a case of primary lymphoma of the gallbladder in an 85-year-old man with gallstone disease, who was admitted for elective cholecystectomy 2 months after an episode of acute cholecystitis and pancreatitis. Histological evaluation of the specimen revealed a small lymphocytic lymphoma of the gallbladder. This type of primary gallbladder lymphoma has not been previously reported. Discussion. The most common primary lymphomas of the gallbladder are MALT lymphomas and diffuse large B-cell lymphomas, although a variety of other histological types have been reported. The association of these lesions with chronic inflammation is the most convincing theory for their pathogenesis. For lesions confined to the gallbladder, cholecystectomy is considered to be sufficient, while supplementary chemotherapy significantly improves prognosis in more advanced disease.

    We developed a novel method of endoscopic subserosal dissection (ESSD) for removal of subepithelial tumors (SETs) originating from the muscularis propria (MP) layer in the upper gastrointestinal (GI) tract. The aim of this study was to evaluate the efficacy, safety, and clinical outcome of this method. Eleven patients with upper GI SETs originating from the MP layer were treated by ESSD between October 2016 and March 2017. ESSD technique consists of six major procedures: (1) incising the mucosal and submucosal layer around the lesion and exposing MP layer; (2) continuous injection was performed while the injection needle slowly moved from the MP layer toward the subserosal layer; (3) incising MP layer; (4) subserosal injection was performed to further separate the serosa from the MP layer; (5) the mucosa, submucosa, and MP layer including SET were carefully dissected en bloc; and (6) closure of the gastric-wall defect with endoscopic techniques. Primary outcome including clinical procedural success and procedure-related adverse events were documented. ESSD was successfully performed in 11 patients. The complete resection rate was 100%, and the mean operation time was 51 (range 22-76) min. The mean resected lesion size was 27 (range 15-40) mm. Pathological diagnosis of these lesions included gastrointestinal stromal tumors (8/11), heterotopic pancreas (1/11), hamartoma (1/11), and leiomyoma (1/11). The small perforations occurred in two patients (4 × 4 and 5 × 5 mm, respectively) during the operation. All perforations and defects were closed successfully by endoscopic techniques. No GI bleeding, peritonitis, abdominal abscess, and other adverse events were observed. No lesion residual or recurrence was found during the follow-up period (mean 18 weeks; range 10-29 weeks). ESSD seems to be an efficacious, safe, and minimally invasive treatment for patients with upper GI SETs originating from the MP layer, making it possible to resect deep lesions, provide

    Extracorporeal shock wave lithotripsy (ESWI.) with adjunctive oral litholytic therapy has proven to be a useful treatment in selected patients with gallbladder stones. To study the effect of ESWL on gallbladder dynamics, {sup 99m}Tc-DISIDA hepatobiliary scintigraphy was done for 25 patients with symptomatic gallstones and 10 normal controls. Of these 25 patients, 15 were treated with ESWL and adjunctive oral litholytic agents (ESWL group) and 10 were treated only with oral litholytic agents (UDCA group). After overnight fast and gallbladder visualization on a routine hepatobiliary scintigraphy with 7 mCi of {sup 99m}Tc-DISIDA, subjects were given fatty meal and imaged with a gamma camera interfaced to a computer (I frame/minute for 70 minutes). A gallbladder time-activity curve was generated and latent period (LP), ejection period (EP), ejection fraction (EF) and ejection rate (ER) were calculated, ESWL group were studied before, l day after and 2 weeks after ESWL, and UDCA group were studied before and 2 weeks after starting oral medication Mean basal EF was significantly reduced in patients but other parameters were not reduced. In ESlVL group, mean EF and mean ER at 1 day after ESWL were reduced. In 3 of them, gallbladder was not visualized at all. Two weeks after ESWL, however, all parameters were recovered to basal level. In UDCA group, all parameters were not changed significantly during medication. We can conclude that ESWL has such immediate adverse effect on gallbladder dynamics as reducing contractility and nonvisualization of gallbladder but it has no long-term effect.

    Gallbladder perforation often occurs during laparoscopic cholecystectomy. The frequency and causes of gallbladder perforation as well as the relevant clinical background factors were investigated in 110 patients undergoing laparoscopic cholecystectomy. We also evaluated intraperitoneal contamination by bacteria and gallstones at the time of gallbladder perforation and investigated whether perforation caused early or late postoperative complications. Intraoperative gallbladder perforation occurred in 29 of the 110 patients (26.3%). It was caused by injury with an electric knife during dissection of the gallbladder bed, injury during gallbladder retraction with grasping forceps, injury during gallbladder extraction from the abdomen, and slippage of cystic duct clips (potentially causing bile and stone spillage). Perforation was more frequent in patients with positive bile cultures and in those with pigment stones (p gallbladder perforation is sometimes unavoidable during laparoscopic cholecystectomy, the risk of severe complications appears to be minimized by early closure of perforation, retrieval of as many of the spilled stones as possible, and intraperitoneal lavage.

Histopathologic sections were prepared from injured tissues and for bacteriology, contents of injured and normal gallbladders were cultured. Major macroscopic changes that were observed in damaged livers and gallbladders were: increasing of gallbladder thickness, petechiae, choleliths in gallbladder, hepatolithiasis, hepatic fascioliasis and presence of dicrocoelium in gall bladder. Histological sections were stained by hematoxylin and eosin, periodic acid schiff and masson’s trichrome staining methods. Cholecystitis, hyperplasia of seromucosal glands’ congestion, hemorrhage, fat necrosis and increased thickness of gallbladder layers were observed. Also Escherichia coli was isolated from 4 gallbladders. In females, the incidence of microscopic changes including cholecystitis, increasing of mucosal layer thickness, hyperplasia of seromucosal glands, hemorrhage in layers except the mucosal layer and presence of bacteria in culture of gallbladder contents was more than males (p

    Porcelain gallbladder is an uncommon manifestation of chronic cholecystitis. The wall of the gallbladder becomes hard, calcified and brittle with a bluish–white tinge which resembles a porcelain ceramic. This condition is associated with increased risk of malignancy. We report two cases, both female patients (both 56 years old) who were diagnosed with porcelain gallbladder. One presented with a pyogenic liver abscess and the other was diagnosed to have gallbladder carcinoma on the background ...

    Full Text Available Double gallbladder is a rare embryological anomaly of clinical significance. Despite availability of modern imaging, only 50% of recently reported cases had preoperative diagnosis, which is desirable in every case to avoid serious operative complications. Double pathology in double gallbladder is extremely rare with only 3 reporting′s available till date to the best of author′s knowledge. With a preoperative diagnosis of double gallbladder, laparoscopic cholecystectomy can be safely and successfully performed with meticulous dissection, aided by operative cholangiogram. However in all such attempts a lower threshold should be kept for conversion to open surgery. Awareness about this anomaly amongst radiologists and surgeons is of crucial importance. Double gallbladder does not present with any specific symptom, neither it increases disease possibility in either lobe. Prophylactic cholecystectomy has no role in asymptomatic cases diagnosed accidentally. Author reports a case of a symptomatic young male with double gallbladder who presented with short history of dyspepsia, abdominal pain and fever. Definite preoperative diagnosis was reached with ultrasound scan and magnetic resonance cholangio pancreatography and subsequently dealt with laparoscopically. Calculous cholecystitis affected one lobe and acalculous empyema the other. While the 1st lobe drained though a cystic duct into common bile duct (CBD, the 2nd was without any communication with either CBD or its counterpart, thus remained as a blind vesicle.

    Topical dissolution of cholesterol gallbladder stones using methyl tert-butyl ether (MTBE) is useful in symptomatic patients judged too ill for surgery. Previous studies showed that ethyl propionate (EP), a C5 ester, dissolves cholesterol gallstones rapidly in vitro, but differs from MTBE in being eliminated so rapidly by the liver that blood levels remain undetectable. Our aim was to test EP as a topical dissolution agent for cholesterol gallbladder stones. Five high-risk patients underwent topical dissolution of gallbladder stones by EP. In three patients, the solvent was instilled via a cholecystostomy tube placed previously to treat acute cholecystitis; in two patients, a percutaneous transhepatic catheter was placed in the gallbladder electively. Gallstone dissolution was assessed by chromatography, by gravimetry, and by catheter cholecystography. Total dissolution of gallstones was obtained in four patients after 6-10 hr of lavage; in the fifth patient, partial gallstone dissolution facilitated basketing of the stones. In two patients, cholesterol dissolution was measured and averaged 30 mg/min. Side effects were limited to one episode of transient hypotension and pain at the infusion site; no patient developed somnolence or nausea. Gallstone elimination was associated with relief of symptoms. EP is an acceptable alternative to MTBE for topical dissolution of cholesterol gallbladder stones in high-risk patients. The lower volatility and rapid hepatic extraction of EP suggest that it may be preferable to MTBE in this investigational procedure.

  19. New approach to gallbladder ultrasonic images analysis and lesions recognition.

    This paper presents a new approach to gallbladder ultrasonic image processing and analysis towards detection of disease symptoms on processed images. First, in this paper, there is presented a new method of filtering gallbladder contours from USG images. A major stage in this filtration is to segment and section off areas occupied by the said organ. In most cases this procedure is based on filtration that plays a key role in the process of diagnosing pathological changes. Unfortunately ultrasound images present among the most troublesome methods of analysis owing to the echogenic inconsistency of structures under observation. This paper provides for an inventive algorithm for the holistic extraction of gallbladder image contours. The algorithm is based on rank filtration, as well as on the analysis of histogram sections on tested organs. The second part concerns detecting lesion symptoms of the gallbladder. Automating a process of diagnosis always comes down to developing algorithms used to analyze the object of such diagnosis and verify the occurrence of symptoms related to given affection. Usually the final stage is to make a diagnosis based on the detected symptoms. This last stage can be carried out through either dedicated expert systems or more classic pattern analysis approach like using rules to determine illness basing on detected symptoms. This paper discusses the pattern analysis algorithms for gallbladder image interpretation towards classification of the most frequent illness symptoms of this organ.

    Full Text Available Hepatomegaly, decrease in the liver paranchymal echo and increase in the gallbladder wall thickness has been shown in acute viral hepatitis. The present study was done to determine sonographic changes in acute viral hepatitis. We performed liver and bile ducts sonography and specific tests on 42 patients (mean age: 31.5 and 61% male with acute viral hepatitis. Gallbladder wall thickness was seen in 45.2% and hepatomegaly in 33.3% of patients and liver paranchymal echo was decreased in 19.3%. Age, sex, type of hepatitis, cholecystitis like symptoms, aspartate aminotransfrase, alanine aminotransfrase, alkaline phosphatase and bilirubin did not significantly corralate with these changes. Only raised prothrombin time was strongly correlated to the thickening of the gallbladder and decrease in the liver paranchymal echo and cholesistic like symptoms we can postulate that thickening of the gallbladder and decrease in the liver paranchymal echo is not dependent on the severity and speed of the paranchymal necrosis (as considered with ALT and AST but they depend on the liver function disturbance (as considered with PT because the thickening of the gall bladder is present in 45% of the patients and 10% of the normal population have gallbladder stones, one should not perform the diagnosis of acute cholecystitis, only on the basis of sonographic report without attention to the clinical and laboratory data.

    The number and rate of cholecystectomy are increasing worldwide, although indications for operative treatment remain empirical, and several issues in the understanding of the condition are not concisely outlined. Our intention is to summarize and interpret current opinion regarding the indications and timing of cholecystectomy in calculous gallbladder disease. Publications concerned with gallstone disease and related topics were searched for in MEDLINE using PubMed and summarized according to clinical scenarios with an emphasis on recent research. Only one randomized controlled trial has investigated the management (conservative vs. surgery) of patients with acute cholecystitis and several have compared early with deferred surgery. Two RCTs have examined treatment of uncomplicated, symptomatic gallstone disease. Apart from these, the overwhelming majority of publications are retrospective case series. Recent literature confirms that cholecystectomy for an asymptomatic or incidental gallstone is not justified. Symptomatic, uncomplicated gallstone disease may be classified into four severity groups based on severity and frequency of pain attacks, which may guide indication for cholecystectomy. Most patients below the age of 70 seem to prefer operative treatment. Acute cholecystitis may be treated with early operation if reduction of hospital days is an issue. Patients older than 70 years with significant comorbidities may forego surgical treatment without undue hazard. Symptoms following cholecystectomy remain in 25% or more and recent evidence suggest these are caused by a functional gastrointestinal disorder.

    1989-01-01

    In evaluating fatty liver with CT, the residual normal liver tissues without fat deposits are occasionally detected on CT as high attenuation regions, especially surrounding the gallbladder. This study examined the incidence of this phenomenon in terms of the diagnostic value of CT in fatty liver. Fifty-seven patients with fatty liver were examined with CT. The incidence of focal sparing area was the highest in the gallbladder bed (42/57, 74%), followed by the interlobar fissure or subcapsular area (13, 23%), quadrate lobe (8, 14%), caudate lobe (2, 4%), and right lobe (one, 1.8%). These CT appearances were of spot, band, ring, and the mixed type. In 38 patients, fatty liver was too moderate to be detected without CT attenuation numbers. Among them, 27 patients (71%) had focal sparing area surrounding the gallbladder. This CT appearance seemed to be of significance in preventing the missing of moderate fatty liver. (Namekawa, K)

    Laparoscopic cholecystectomy (VALC) represents the treatment of choice for the symptomatic gallstones. However the occurrence of an adenocarcinoma of the gallbladder results a controindication for this surgical technique. We present a case of a 52 years old woman who underwent a VALC; histology revealed a gallbladder adenocarcinoma. For this reason the patient underwent a second operation that is right hepatic trisegmentectomy. Six months later the patient presented with a parietal recurrence at the extraction site of the gallbladder. We discuss the possible mechanism responsible for carcinomatous dissemination during laparoscopic surgery and we raccommend the use of some procedures in order to limit the risk and eventually to treat a neoplastic parietal seeding. These complications suggest the problem about the utility and the future played by video assisted laparoscopic surgery in the diagnosis and treatment of intraabdominal malignancies.

    Full Text Available Objective To investigate the value of laparoscopic gallbladder-preserving partial cholecystectomy in the treatment of abnormal gallbladder morphology complicated by sand-like calculous cholecystitis. Methods A total of 18 patients with abnormal gallbladder morphology complicated by sand-like calculous cholecystitis who underwent laparoscopic and choledochoscopic partial cholecystectomy in Dalian Friendship Hospital from July 2010 to January 2014 were enrolled. All the patients had abnormal gallbladder morphology manifested as folded gallbladder or adenomyosis, and the lesions were located in the distal end of the gallbladder. Before the surgery, gallbladder contraction test was performed for the diseased part and the normal part of the gallbladder to be preserved. During the surgery, choledochoscopy showed an unobstructed cystic duct and good elasticity in the gallbladder wall, and there was no marked chronic inflammation. After the diseased part of the gallbladder was removed, 4-0 absorbable suture was used for two-layer consecutive suture of the gallbladder. The t-test was used for comparison of continuous data between groups. Results All the patients underwent the surgery successfully. The mean time of operation was 98.0±9.0 minutes, and the mean time to first flatus was 22.8±2.5 hours. The patients were able to get out of the bed and drink water at 6 hours after surgery and to have meals at 24 hours after surgery. They fully recovered and were discharged at 5-7 days after surgery, and no patient experienced the complications such as bile leakage. The patients were followed up for 6-80 months; the patients′ preoperative clinical symptoms disappeared, and there was no recurrence of calculi. At 6-12 months after surgery, the patients experienced compensated cholecystectasis, and there was a significant increase in the mean volume of the gallbladder after surgery (30.29±4.23 cm3 vs 21.72±4.34 cm3, t=-13.00, P<0.001.

    The role of minimally invasive surgery in the surgical management of gallbladder cancer is a matter of controversy. Because of the authors' growing experience with laparoscopic liver and pancreatic surgery, they have begun offering patients laparoscopic completion partial hepatectomies of the gallbladder bed with laparoscopic hepatoduodenal lymphadenectomy. The video shows the steps needed to perform laparoscopic resection of the residual gallbladder bed, the hepatoduodenal lymph node nodes, and the residual cystic duct stump in a setting with a positive cystic stump margin. The skin and fascia around the previous extraction site are resected, and this site is used for specimen retrieval during the second operation. To date, three patients have undergone laparoscopic radical cholecystectomy with hepatoduodenal lymph node dissection for gallbladder cancer. The average number of lymph nodes retrieved was 3 (range, 1-6), and the average estimated blood loss was 117 ml (range, 50-200 ml). The average operative time was 227 min (range, 120-360 min), and the average hospital length of stay was 4 days (range, 3-5 days). No morbidity or mortality was observed during 90 days of follow-up for each patient. Although controversy exists as to the best surgical approach for gallbladder cancer diagnosed after routine laparoscopic cholecystectomy, the minimally invasive approach seems feasible and safe, even after previous hepatobiliary surgery. If the previous extraction site cannot be ascertained, all port sites can be excised locally. Larger studies are needed to determine whether the minimally invasive approach to postoperatively diagnosed early-stage gallbladder cancer has any drawbacks.

Magnetic resonance cholangiopancreatography revealed a dilated common channel of intrahepatic bile duct of segment 3 (B3 and segment 4 (B4 drained into the gallbladder directly. The patient underwent laparoscopic cholecystectomy and Roux-en Y hepaticojejunostomy (B3-jejunostomy. Among the anatomical variability of the biliary system, the cholecystohepatic ducts are controversial in existence and incidence. We report a very rare variant of a cholecystohepatic duct in which the B3 duct drained into gallbladder directly and to the best of our knowledge this is the first report.

    Although many alternative treatment technics have been proposed recently for gallstone to substitute cholecystectomy, the extracorporeal shock wave lithotripsy (ESWL) for gallbladder stones has rarely been tried. We have carried out a series of experiments to evaluate how effective the ESWL for gallbladder stones in and how safe this procedure is. At first, in vitro shock were application was carried out to 10 gallbladder stones which were obtained from human gallbladder. Secondly, gallbladder stones were implanted to canine gallbladder and treated with shock wave. Lastly, a total of 41 volunteers with confirmed gallbladder stones were treated with shock wave and combined oral administration of ursodeoxycholic acid. In the in vitro experiment, all of the 10 gallstones were fragmented with variable firing rates and duration. In animal experiment, the implanted stones were successfully fragmented and the organs included in the pathway of shock wave were proved to be intact histologically. In human study, complete disappearance of gallstones was noted in 78.6% of patients with single radiolucent gallbladder stones, smaller than 2.5cm in the longest diameter. Two patients underwent cholecystectomy after ESWL due to sudden colic attack. One patient had experienced an episode of mild transient obstructive jaundice. It may be concluded that the ESWL for gallbladder stones is an effective and safe method of treatment of gallbladder stones in the selected cases, for example, small radiolucent stones, and the further study is needed to establish improved technology of the ESWL for gallbladder stones.

    2006-01-01

    Because thickening of the gallbladder wall is observed not only in patients with gallbladder cancer but also in those with benign diseases such as chronic cholecystitis and gallbladder adenomyosis, it is difficult to distinguish between benign and malignant gallbladder wall thickening by conventional techniques of diagnostic imaging such as computed tomography (CT), magnetic resonance imaging (MRI), and abdominal ultrasonography (US). In the present study, we attempted to distinguish between benign and malignant gallbladder wall thickening by means of fluorine-18-fluorodeoxyglucose (FDG)-Positron emission tomography (PET). FDG-PET was performed in 12 patients with gallbladder wall thickening detected by CT or US, to determine whether it was benign or malignant. Emission scans were taken, beginning 45 minutes after intravenous administration of FDG, and standardized uptake value (SUV) was calculated as an indicator of glucose metabolism. Of the 12 patients, 4 showed positive uptake of FDG in the gallbladder wall. Of these 4 patients, 3 had gallbladder cancer. The remaining one, who had chronic cholecystitis, had false-positive findings. The other 8 patients had negative uptake of FDG in the gallbladder wall. Two of these 8 underwent surgical resection, which yielded a diagnosis of chronic cholecystitis. The other 6 patients exhibited no sign of gallbladder malignancy and have been followed without active treatment. FDG-PET appears able to distinguish between benign and malignant gallbladder wall thickening. (author)

    Ultrasonic dissection has been suggested as an alternative to monopolar electrocautery in laparoscopic cholecystectomy because it generates less tissue damage and may have a lower incidence of gallbladder perforation. We compared the 2 methods to determine the incidence of gallbladder perforation and its intraoperative consequences. We conducted a prospective randomized controlled trial between July 2008 and December 2009 involving adult patients with symptomatic gall stone disease who were eligible for laparoscopic cholecystectomy. Patients were randomly assigned before administration of anesthesia to electrocautery or ultrasonic dissection. Both groups were compared for incidence of gallbladder perforation during dissection, bile leak, stones spillage, lens cleaning, duration of surgery and estimation of risk of gallbladder in the presence of complicating factors. We included 60 adult patients in our study. The groups were comparable with respect to demographic characteristics, symptomatology, comorbidities, previous abdominal surgeries, preoperative ultrasonography findings and intraoperative complications. The overall incidence of gallbladder perforation was 28.3% (40.0% in the electrocautery v. 16.7% in the ultrasonic dissection group, p = 0.045). Bile leak occurred in 40.0% of patients in the electrocautery group and 16.7% of patients in ultrasonic group (p = 0.045). Lens cleaning time (p = 0.015) and duration of surgery (p = 0.001) were longer in the electrocautery than the ultrasonic dissection group. There was no statistical difference in stone spillage between the groups (p = 0.62). Ultrasonic dissection is safe and effective, and it improves the operative course of laparoscopic cholecystectomy by reducing the incidence of gallbladder perforation.

    Gallbladder perforation is a serious clinical condition and associated with high morbidity and mortality. A definitive diagnosis is contentious before surgery. We herein report a case of perforation of the gallbladder neck secondary to chemotherapy and radiation for nasopharyngeal carcinoma patient. Gallbladder perforation secondary to chemotherapy and radiation. To decrease the mortality associated with gallbladder perforation, Laparoscopic cholecystectomy and peritoneal lavage were performed followed for gallbladder perforation patient because of chemotherapy and radiation. The patient recovered fully without serious complication and discharged on the 10th postoperative day. A pathological examination of the resected gallbladder revealed cholecystitis in the thinning of the neck. Early diagnosis and surgical intervention of gallbladder perforation in relation to asopharyngeal carcinoma chemotherapy and radiation are of prime importance. The laparoscopic procedure is safe and feasible in the selected patients.

    To reestablish the size criterion of the gallbladder on ultrasonography (US) for the differentiation diagnosis of biliary atresia from neonatal hepatitis. Abdominal US ws performed in 201 patients with jaundice and 40 patients without evidence of jaundice or hepatobiliary illness (all with the age less than 4 months). US was performed in fasting (fasting for at least 4 hours) to measure the length of the gallbladder and calculated the area of the gallbladder lumen. The morphology of the gallbladder was classified into three types: normal, elongated and atretic. To evaluate the contractibility of the gallbladder, the length of the gallbladder and area of the gallbladder lumen was again measured 1 hour after feeding. The final diagnosis included biliary atresia in 79 patients and neonatal hepatitis in 83 patients. Differences in the length, area, and morphology of the gallbladder were statistically significant among three groups, the normal group, neonatal hepatitis group and biliary atresia group (length and area of gallbladder; normal group>neonatal hepatitis>biliary atresia). The differences in the length and area of gallbladder between pre- and postmeal state were statistically significant in the normal and neonatal hepatitis groups whereas those of biliary atresia were not significant (p=0.85). When the empirical size criterion of the gallbladder (<15 mm in length) was applied, the sensitivity, specificity and diagnostic accuracy for the differential diagnosis of biliary atresia from hepatitis were 52%, 82%, and 67%, respectively. Meanwhile, if the area criterion(<30 mm{sup 2} in area) was applied, the sensitivity, the specificity and diagnostic accuracy were 67%, 85%, and 75%, respectively. Ultrasonographic evaluation of the morphology as well as size of the gallbladder are helpful in the differential diagnosis of biliary atresia from neonatal hepatitis. Therefore, since the measurement of the area of gallbladder lumen on US reflect both size and morphology of

    The aim of this study was to examine the microsatellite instability (MSI) and loss of heterozygosity (LOH) of locus D17S396 on chromosome 17 and their influence on the expression of nm23H1 in gallbladder tumors, which may provide experimental basis for the tumor occurrence and metastasis. Techniques such as DNA extraction from formalin-fixed paraffin-embedded tissues, polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP), ordinary silver stain were used to study MSI and LOH of locus D17S396. Envision immunohistochemistry and Leica-Qwin computer imaging techniques were used to assess the expression of gene nm23H1. In our experiment, the frequency of genetic instability of malignant gallbladder tumors was 42.55%, which was higher than that of gallbladder adenomas, while there were no genetic instability occurred in chronic cholecystitis tissue. The frequency of LOH seemed higher with the deteriorism of gallbladder tumor. Among 47 gallbladder carcinomas, the frequency of LOH and MSI were different between different differentiation cases (P gallbladder carcinoma, gallbladder adenoma and chronic cholecystitis tissue were different (P gallbladder carcinomas, the positive frequency of nm23H1 protein in LOH positive group was lower than that of LOH negative group (P gallbladder tumor. Both MSI and LOH of nm23H1 gene controlled the development of gallbladder tumor independently in different paths. MSI may be an early stage molecule marker of gallbladder carcinoma. LOH may be molecule marker for the deteriorism of gallbladder tissue, which could inhibit the expression of nm23H1 in local tissue of gallbladder carcinoma and endow it with high aggressive and poor prognosis. Increasing the amount of nm23H1 protein expression could effectively restrain gallbladder carcinoma metastasis and improve prognosis of patients.

    -induced GLP1 secretion combined with the findings of reduced postprandial gallbladder emptying in patients with type 2 diabetes (T2DM) led us to speculate whether reduced postprandial GLP1 responses in some patients with T2DM arise as a consequence of diabetic gallbladder dysmotility. DESIGN AND METHODS......: In a randomised design, 15 patients with long-standing T2DM and 15 healthy age-, gender- and BMI-matched control subjects were studied during 75-g oral glucose tolerance test (OGTT) and three isocaloric (500 kcal) and isovolaemic (350 ml) liquid meals: i) 2.5 g fat, 107 g carbohydrate and 13 g protein; ii) 10 g...... secretion was similar after both OGTT and meals. CONCLUSIONS: In conclusion, patients with T2DM exhibited normal gallbladder emptying to meals with a wide range of fat content. Incretin responses were similar to that in controls, and an association with postprandial gallbladder contraction could...

    A case of heterotopic gastric mucosa in the common bile duct, cystic duct and gallbladder is reported in a 3-year-old girl with abdominal pain and jaundice. Abdominal US and CT showed dilatation of the biliary tree and a well-defined mass in the common bile duct that narrowed its lumen. The gallbladder was contracted in both examinations. The common bile duct and the gallbladder were resected and a choledochojejunostomy was performed. Although gastric heterotopy has been described throughout the entire length of the gastrointestinal tract, it is a very uncommon finding in the gallbladder and extremely rare in the biliary tree. A firm diagnosis of gastric heterotopia is based on the presence of fundal mucosa replete with parietal and chief cells. To our knowledge, this is the fifth reported case of heterotopic gastric tissue within the common bile duct, and the first to describe the US and CT findings. A relevant literature review and brief outline of the histological and radiological features are included in the discussion. (orig.)

    A preliminary study of the relation between food intake and intensity of gallbladder bile on nuclear magnetic resonance (NMR) images was made. Twelve subjects (seven volunteers, five patients) were imaged following a minimum of 14 hours of fasting. Six of seven volunteers were reimaged one hour after stimulation by either a fatty meal or an alcoholic beverage. An additional seven patients were imaged two hours after a hospital breakfast. It was found that concentrated bile emits a high-intensity spin echo signal (SE), while hepatic bile in the gallbladder produces a low-intensity SE signal. Following ingestion of cholecystogogue, dilute hepatic bile settles on top of the concentrated bile, each emitting SE signals of different intensity. The average T1 value of concentrated bile was 594 msec, while the T1 vaue of dilute hepatic bile was 2,646 msec. The average T2 values were 104 msec for concentrated bile and 126 msec for dilute bile. The most likely cause for the different SE intensities of bile is the higher water content, and therefore longer T1 or T2 relaxation times, of hepatic bile. It is suggested that NMR imaging has the ability to provide physiological information about the gallbladder and that it may prove to be a simple and safe clinical test of gallbladder function

    2011-04-01

    Full Text Available Abstract Acute gallbladder volvulus continues to remain a relatively uncommon process, manifesting itself usually during exploration for an acute surgical abdomen with a presumptive diagnosis of acute cholecystitis. The pathophysiology is that of mechanical organo-axial torsion along the gallbladder's longitudinal axis involving the cystic duct and cystic artery, and with a pre-requisite of local mesenteric redundancy. The demographic tendency is septua- and octo-genarians of the female sex, and its overall incidence is increasing, this being attributed to increasing life expectancy. We discuss two cases of elderly, fragile women presenting to the emergency department complaining of sudden onset right upper quadrant abdominal pain. Their subsequent evaluation suggested acute cholecystitis. Ultimately both were taken to the operating room where the correct diagnosis of gallbladder torsion was made. Pre-operative diagnosis continues to be a major challenge with only 4 cases reported in the literature diagnosed with pre-operative imaging; the remainder were found intra-operatively. Consequently, a delay in diagnosis can have devastating patient outcomes. Herein we propose a necessary high index of suspicion for gallbladder volvulus in the outlined patient demographic with symptoms and signs mimicking acute cholecystitis.

    Full Text Available Introduction: Hepatic choristomas or ectopic livers are uncommon, and occur due to a failure of embryological liver development. They pose a risk of carcinogenesis, with transformation to hepatocellular carcinoma (HCC being described in the literature (Arakawa et al., 1999. It is often a silent clinical finding that can occur anywhere in the body and is usually diagnosed incidentally during abdominal surgical procedures or autopsies (Eiserth et al., 1940. We present the case of a patient with a symptomatic ectopic liver that was detected preoperatively, and removed laparoscopically with the gallbladder. Presentation of case: A 73-year-old lady was referred to our unit for a gallbladder tumor on ultrasound which was done for biliary colic. Tumor markers were normal. Computed tomography (CT scan showed an enhanced soft tissue lesion measuring about 3 × 1.5 cm interposed between the gallbladder and liver. Laparoscopic exploration revealed a bean-shaped hepatic choristoma attached to the liver on the medial wall of the gallbladder. The lesion was removed by en-bloc resection during laparoscopic cholecystectomy and extracted carefully in an endobag. Histopathological examination confirmed the absence of carcinogenesis. Discussion and conclusion: Hepatic choristomas (HC are a rare entity, usually identified during abdominal surgeries. It had been reported in several studies with different presentations. Awareness of this unexpected finding and familiarity of its potential complications and carcinogenesis will improve care delivery when encountered. Surgical treatment should be considered when the choristoma is not attached to the liver, in light of its potential transformation into HCC.

    Gallbladder perforation (GBP) is a rare disease with potential mortality. Previous series have reported an incidence of approximately 2-11% and it still continues to be a significant problem for surgeons. To present our clinical experience with gallbladder perforation. The records of 2754 patients who received surgical treatment for cholelithiasis between 2010 and 2016 were reviewed retrospectively. One hundred thirty-three patients had gallbladder perforation. Age, gender, time from the onset of symptoms, diagnostic procedures, surgical treatment, morbidity and mortality rates were evaluated. 15.78% of patients had a body mass index > 35. 6.76% had chronic obstructive pulmonary disease, 6.76% had cardiac disease, 10.52% had diabetes and 4.51% had sepsis. American Society of Anesthesiology scores were I in 54.13%, II in 35.33%, III in 6.01% and IV in 4.51% of the patients. 27.81% of patients were diagnosed during surgery. The perforation site was the gallbladder fundus in 69.17%, body in 17.30%, Hartman's pouch in 10.53% and cystic duct in 3% of patients. Treatment modalities were laparoscopic cholecystectomy in 82.71%, open cholecystectomy in 3%, percutaneous drainage catheters + laparoscopic cholecystectomy in 3%, laparoscopic cholecystectomy + fistula repair in 10.53% and open cholecystectomy + fistula repair in 0.75% of patients. Mean length of hospital stay was 1.69 days. Mortality and morbidity rates were 8.27% and 10.52%, respectively. Histopathology results were acute cholecystitis in 69.93%, chronic cholecystitis in 20.30% and acute exacerbation over chronic cholecystitis in 9.77% of patients. Appropriate classification and management of perforated cholecystitis is essential. Laparoscopic cholecystectomy is a safe and feasible method to decrease morbidity in gallbladder perforations.

    We studied gallbladder bile flow before, during, and after cholesterol gallstone formation in the prairie dog using infusion cholescintigraphy with /sup 99m/Tc-diethyl iminodiacetic acid. In 18 fasting animals partitioning of bile between gallbladder and intestine was determined every 15 min for 140 min, and gallbladder response to cholecystokinin (5 U/kg X h) was calculated from the gallbladder ejection fraction. Ten prairie dogs were then placed on a 0.4% cholesterol diet and 8 on a regular diet, and the studies were repeated 1, 2, and 6 wk later. The proportion of hepatic bile that entered the gallbladder relative to the intestine varied from one 15-min period to the next, and averaged 28.2% +/- 5.1% at 140 min. Partial spontaneous gallbladder emptying (ejection fraction 11.5% +/- 5.6%) was intermittently observed. Neither the number nor the ejection fraction of spontaneous gallbladder contractions changed during gallstone formation. By contrast, the percent of gallbladder emptying in response to cholecystokinin decreased from 72.1% +/- 5% to 25.9% +/- 9.3% (p less than 0.025) in the first week and was 14.3% +/- 5.5% at 6 wk (p less than 0.01 from prediet values, not significant from first week). Gallbladder filling decreased from 28.2% +/- 5.1% to 6.7% +/- 3% (p less than 0.01), but this change was only observed after 6 wk, when gallstones had formed. This study shows that bile flow into the gallbladder during fasting is not constant; the gallbladder contracts intermittently; gallbladder emptying in response to exogenous cholecystokinin is altered very early during gallstone formation; and gallbladder filling remains unaffected until later stages, when gallstones have formed

    Objective. Earlier we shown that Cholecystokinetic effect of balneotherapy on spa Truskavets’ may be the result of modulation of neuroendocrine-immune complex. The aim of present investigation: clarification relationships between parameters of gallbladder motility and ongoing Electroencephalogram (EEG as well as Heart Rate Variability (HRV. Material and Methods. At 22 men with chronic cholecystite combined with pyelonephrite we recorded twice basal and postprandial volume of gallbladder (Echoscopy by “Radmir”, EEG ("NeuroCom Standard" and HRV ("CardioLab+HRV". Results. Basal gallbladder volume correlated positively with HRV markers of Vagal tone (HF, RMSSD, pNN50 and relative Power Spectrum Density (PSD C4-δ while negatively with Amplitude of β-Rhythm and its absolute PSD in loci P3, P4, Fp1, C3, F3, F4 as well as PSD T3-δ and Frequency of α-Rhythm. Canonical correlation is very strong: R=0,96; Adjusted R2=0,85; χ2(15=61; p<10-5. Gallbladder volume after 5 min after taking of Cholekinetik (50 ml of 40% solution of xylitol, expressed as portion its basal volume, correlated positively with VLF, Deviation of θ-Rhythm and its relative PSD in loci F4, P4 and P3 while negatively with relative PSD O1-θ and absolute PSD P4-β and T6-β as well as Asymmetry of θ-Rhythm. Canonical correlation is very strong too: R=0,87; Adjusted R2=0,66; χ2(9=38; p<10-4. As distinct from early next postprandial volumes significantly less liable to neural regulatory influences: R makes 0,67 (p=0,003 and 0,60 (p=0,009 after 15 and 30 min respectively. In particular, both V15 and V30 equal positively correlated with HF and Laterality of α-Rhythm, however V15 correlated with Asymmetry of θ-Rhythm (r=-0,45 and its PSD in loci F3 (r=0,28 and C4 (r=0,27, while V30 correlated with Asymmetry of δ-Rhythm (r=-0,28 and PSD C4-β (r=-0,34.

    Full Text Available Fasting and postprandial gallbladder volumes were investigated using ultrasonography in three groups (10 subjects in each of healthy women: third trimester pregnant women, postpartum women up to 10 days after giving birth and nonpregnant controls. The scans were performed at 09:00 after a 12 h fast. After the basal measurement was taken, gallbladder volumes were rescanned in 15 min intervals for 60 mins. At the end of this period, all volunteers received a standard liquid test meal, and scans were performed again for 1 h. The mean basal gallbladder volume was 22.2±4.2 mL in the nonpregnant (control group. In the third trimester group, the basal volume was 37.8±10.5 mL – 70.5% higher than in the nonpregnant group (P<0.001. In the postpartum group, the mean basal volume was 37.9% lower (27.4±6.5 mL than that of the third trimester group (P<0.02. This basal volume was 23.6% greater than that of the control group (P<0.05. After administration of a test meal, the postprandial gallbladder volumes decreased during the first few minutes compared with baseline values. The volumes decreased by 10.2% to 39.8% (23.5±7.3 to 34.0±10.2; P<0.01 in the third trimester group, by 14.9% to 43.2% (16.6±4.3 to 23.3±5.5; P<0.01, 0.001 in the postpartum group and by 19.2% to 51.6% (11.9±3.5 to 17.9±3.6; P<0.02, 0.05, 0.01, 0.001 in the control group. Postprandial mean gallbladder volumes of the third trimester (P<0.02 and postpartum groups (P<0.02 to 0.01 were significantly different from those of the control group. In conclusion, incomplete emptying of the gallbladder after eating during the third trimester of pregnancy may contribute to cholesterol-gallstone formation, and pregnancy may thus increase the risk of gallstones.

    As a new application of helical (spiral) scan, volume measurement has received a significant interest. Although it is important to evaluate gallbladder contractibility to decide on a treatment plan for a gallbladder lesion, qualitative analysis of gallbladder contractibility is very difficult owing to the fact that the volume of gallbladder can not be measured using usual DIC examination (plain X-P and tomography). In this study, the accuracy of volume measurement of helical CT was checked firstly by gallbladder phantom experiments. Then 128 cases of volume measurement of helical 3D CT Cholangiography (DIC-CT) were performed. Under the conditions of optimized scan technique (3 mm TH, 3 mm/s, 1 mm recon interval, Hispeed, GEMS), the difference of contractibility was obtained between clinical cases with and without thick wall. The experiment has shown that helical 3D CT volume measurement is very simple and highly accurate method which is useful for the evaluation of gallbladder contractibility. (author)

    Cholecystography with 99m Tc-EHIDA was performed to assess the preprandial empty function of gallbladder and then solid meal labelled with 99m Tc-DTPA was given to assess the postprandial empty function of stomach in 25 patients with NUD. The examinations were repeated in 15 patients with hypomotilitic stomach and gallbladder following administration of Domperidone 20 mg t.i.d for four weeks. The results showed that the empty function of stomach was closely related to the amplitude and frequency of antrum contractile peristaltic waves, all NUD patients who had delayed gastric empty also had hypomotilitic gallbladder. This may be one of the pathophysiologic bases of NUD. The movements of stomach and gallbladder both preprandial and postprandial were synchronous. Domperidone can restore hypomotility of stomach and gallbladder in NUD patients to normal, and the movements of stomach and gallbladder still remained synchronous

    Hemobilia secondary to gallbladder polyposis is rare in children but has been reported in a few children with metachromatic leukodystrophy. We present a case with preoperative multidetector computed tomography (MDCT) diagnosis of massive hemobilia caused by gallbladder polyposis in a patient with metachromatic leukodystrophy. Our report highlights the importance of both awareness of the association of gallbladder polyposis with other syndromes such as metachromatic leukodystrophy as well as the possibility of this entity presenting with life-threatening bleeding.

    The growth rate of a single symmetrically oval shaped gallbladder stone weighing 10.8 g was recorded over a period of six years before surgery and removal. The length of the stone was measured by ultrasonography and the growth rate was found to be linear with time, with a value of 0.4 mm/year. A smaller stone growing in the wall of the gallbladder was detected only three years before removal and grew at a rate of ˜ 1.33 mm/year. The morphology and metallic ion chemical composition of the large stone and of a randomly selected small stone weighing about 1.1 g, extracted from another patient, were analyzed and compared. It was found that the large stone contained besides calcium also lead, whereas the small stone contained mainly calcium. It is possible that the lead causes a difference in mechanism between the growth of a single large and growth of multiple small gallstones.

    Aging and female sex are major risk factors for cholesterol gallstones: in addition to hepatic secretion of lithogenic bile, decreased gallbladder contractility may play a role in such physiological conditions. This study was aimed at evaluating the effect of age and sex on gallbladder kinetics in healthy subjects. Gallbladder volume was measured on the US images of 157 fasting subjects using the sum-of-cylinders method. No significant difference was observed between males and females. On the contrary, age was shown to have a significant positive correlation with fasting gallbladder volume, particulary in males. In a second group of 63 healthy volunteers gallbladder volumes were evaluated both before and after a standard meal. The subjects were grouped according to age, and fasting gallbladder volume appeared to be significantly greater in the groups formed by older people. Gallbladder volumes were compared in younger groups (under 35), and gallbladder emptying resulted to be much more complete in males than in females. On the contrary, no significant differences was observed between males and famales over50 - which suggests a possible role of sex - and age-related hormonal factors. The above changes in gallbladder function may facilitate bile stasis which might in turn contribute to the increased risk for cholesterol gallstones notoriously associated with advanced age and female sex

    Gallbladder cancer has poor prognosis and limited therapeutic options. Arctigenin, a representative dibenzylbutyrolactone lignan, occurs in a variety of plants. However, the molecular mechanisms involved in the antitumor effect of arctigenin on gallbladder cancer have not been fully elucidated. The expression levels of epidermal growth factor receptor were examined in 100 matched pairs of gallbladder cancer tissues. A positive correlation between high epidermal growth factor receptor expression levels and poor prognosis was observed in gallbladder cancer tissues. Pharmacological inhibition or inhibition via RNA interference of epidermal growth factor receptor induced cellular senescence in gallbladder cancer cells. The antitumor effect of arctigenin on gallbladder cancer cells was primarily achieved by inducing cellular senescence. In gallbladder cancer cells treated with arctigenin, the expression level of epidermal growth factor receptor significantly decreased. The analysis of the activity of the kinases downstream of epidermal growth factor receptor revealed that the RAF-MEK-ERK signaling pathway was significantly inhibited. Furthermore, the cellular senescence induced by arctigenin could be reverted by pcDNA-epidermal growth factor receptor. Arctigenin also potently inhibited the growth of tumor xenografts, which was accompanied by the downregulation of epidermal growth factor receptor and induction of senescence. This study demonstrates arctigenin could induce cellular senescence in gallbladder cancer through the modulation of epidermal growth factor receptor pathway. These data identify epidermal growth factor receptor as a key regulator in arctigenin-induced gallbladder cancer senescence.

    To test the use of a simple and cheap powder-free glove bag to extract the gallbladder during laparoscopic cholecystectomy (LC). The medical records of 142 consecutive patients who had their gallbladder removed using a powder-free glove bag were reviewed. No complications in the form of bile or stone spillage during extraction were observed. The absence of complications and the low cost make routine use of the glove bag a wise option for extracting the gallbladder during LC. The use of the glove bag seems to reduce the risk of contamination with bacteria, bile, and gallstones and may reduce contamination by malignant cells in case of unexpected gallbladder carcinoma.

Herein, we report the ultrasound, computed tomography and positron emission tomography-computed tomography imaging findings on a case of primary leiomyosarcoma of the gallbladder. Abdominal ultrasonography indicates a heterogeneous hyperechoic submucosal mass with hypervascularity and displacement of overlying mucosal layers by the mass. Computed tomography reveal that the tumor is a well-defined and heterogeneously enhancing solid mass with overlying thick mucosal layers. Positron emission tomography-computed tomography visualizes the large gallbladder mass as a hypermetabolic lesion.

    Cholecystectomy is the current standard recommended treatment for dogs with gallbladder mucoceles. However, medical management with monitoring has also been recommended for asymptomatic dogs. The purpose of this retrospective study was to compare ultrasonographic patterns of gallbladder mucoceles with clinical disease status in a group of dogs. For each included dog, the ultrasonographic pattern of the mucocele was classified into one of six types: type 1, immobile echogenic bile; type 2, incomplete stellate pattern; type 3, typical stellate pattern; type 4, kiwi like pattern and stellate combination; type 5, kiwi like pattern with residual central echogenic bile; and type 6, kiwi like pattern. A total of 43 dogs were included. Twenty-four dogs, including 11 dogs with gallbladder rupture, were symptomatic. Nineteen dogs were asymptomatic. Cholecystectomy (n = 19), medical therapy (n = 17), or monitoring (n = 6) treatments were applied according to clinical signs and owners' requests. One dog suspected of having gallbladder rupture was euthanized. Frequencies of gallbladder mucocele patterns were as follows: type 1 = 10 (23%), type 2 = 13 (30%), type 3 = 5 (12%), type 4 = 11 (26%), type 5 = 4 (9%), and type 6 = 0. In dogs with gallbladder rupture, type 2 (8/13) was the most common. No significant correlations were found between ultrasonographic patterns of gallbladder mucoceles and clinical disease status or gallbladder rupture. Findings indicated that ultrasonographic patterns of gallbladder mucoceles may not be valid bases for treatment recommendations in dogs. © 2013 American College of Veterinary Radiology.

    The present study reports on 51 patients with symptomatic cholecystolithiasis, who accordingly underwent extracorporeal shock-wave lithotripsy (ESWL). In all cases, computed tomography (CT) was performed prior to and after the therapeutic procedure to delineate changes in gall-bladder morphology. Slight edematous thickening of the gall-bladder wall was found in 15 patients. One patient presented a rupture of the gall-bladder with formation of a bilioma in the adjacent liver tissue. In case of calcific concrements, CT revealed a characteristic pattern of fragment distribution following shock-wave treatment, and fragments of various sizes exhibited distinct adhesion to the gall-bladder wall.

    In this era of minimally invasive surgery, the challenge remains in finding techniques to reduce access trauma in terms of fewer and smaller size trocar ports. Our new described technique will allow a smaller subxiphoid port to be used to achieve extraction of the gallbladder without the need to change to a 5 mm laparoscope. We believe this method is easy to learn, safe and with no observable complications from our experience.

    Full Text Available Channel of the gallbladder (DC shows the different anatomical variations, the knowledge is important in the diagnosis and particularly abdominal surgery. The aim of this study was to investigate possible gender differences in the morphology of the gallbladder channel (DC. A total sample consists of 50 anatomical liver taken from autopsy cases of both sexes (32 men and 18 women. Samples of liver were fixed in 4% formalin for 4 weeks, and then studied microdissected under scrutiny. We were working length measurement channels of the gallbladder (DC and typing of junction of the cystic (DC with the common hepatic duct (DHC. We classify anatomical junction variations DC with DHC into three types: angular, parallel and spiral type, and then performed statistical analysis of the data with respect to gender. Results: The angular type compound we found approximately at 2/3 or 64% of the samples (men-60% of women-72%, the parallel type combination of a total of 22% of the sample (men-31% of women-6% and spiral type of 14% of the samples (males-9%, women 22%. Parallel and spiral type together make up about 1/3 of the cases. The average length of DC is 3.1 cm and the variation interval of 1.7 to 6.2 cm. We found that the difference circuit between DC and DHC the angular variable (parallel junction and spiral with respect to gender there but the difference was not statistically significant (p> 0.05.

    Patients with diffuse esophageal spasm (DES) and nutcracker esophagus/high amplitude esophageal contraction (HAEC) have a thicker esophageal muscularis propria than do healthy subjects. The goals of this study were to determine the esophageal muscle cross-sectional area (MCSA), a measure of muscle mass, in patients with achalasia of the esophagus; and to compare it with that in patients with DES, patients with HAEC, and normal subjects. Using a high-frequency ultrasound probe catheter, concurrent manometry and ultrasound images of the esophagus were recorded in four subject groups: normal volunteers, patients with HAEC, patients with DES, and patients with achalasia of the esophagus. Recordings were obtained from the lower esophageal sphincter (LES) and multiple sites in the esophagus 2, 4, 6, 8, and 10 cm above the LES. The LES and esophageal muscle thickness as well as esophageal MCSA were greater in all three patient groups than in the normal subject group. Muscle thickness and MCSA were observed to be greatest in patients with achalasia, which were greater than in patients with DES, which were greater than in those with HAEC, which in turn were greater than in normal subjects. We propose that an increase in the MCSA is an important feature of patients with primary motility disorders of the esophagus. The degree of increase in muscle mass may be an important determinant of the type and the severity of esophageal motor dysfunction.

    Gallbladder disorders have been recognized with increasing frequency in pediatric patients. This study aimed to identify recent trends in management and compare the effectiveness of laparoscopic (LC) over open cholecystectomy (OC) by a retrospective chart analysis of all cholecystectomies from 1990 through 1995. Information obtained included demographics, symptoms, predisposing conditions, associated illnesses, family history, imaging studies, type of cholecystectomy, complications, operative time, pain medication, diet recommencement, pathologic findings, and length of hospital stay. The type of cholecystectomy (OC vs. LC) was compared with the clinical variables using standard statistics. Eighty-three patients between 21 months and 18 years of age were identified; their mean age was 14.8 years. Females (76%) with classic biliary symptoms predominated;12% of the patients developed gallstone pancreatitis and 7% jaundice. Abnormal liver chemistry values, obesity, and elevated triglyceride levels comprised the most significant predisposing factors. Indications for surgery were cholelithiasis in 71 patients (86%), gallbladder dyskinesia in 10 (12%), and sludge/polyp in 2. Fifty-nine cholecystectomies (71%) were done laparoscopically and 24 (29%) open. Choledocholithiasis in 6 children (7%) was managed by open extraction with t-tube placement or endoscopic papillotomy followed by LC. No major ductal complication was identified. The predominant pathologic finding was chronic cholecystitis, including the subgroup with biliary dyskinesia. Statistical comparison showed that LC is superior to OC in regard to length of stay, diet resumption, use of pain medication, operating time, and cosmetic results. It is concluded that a contemporary diet, obesity, and abnormal liver chemistry are the main predisposing conditions of gallbladder disease in children in this decade. Females in their teenage years with typical symptoms continue to be the most commonly affected group

    The purpose of this study was to report our initial experience with a swine model for biliary interventions by using a percutaneous transcholecystic access after suture anchor of the gallbladder. Telepaque tablets were given to five pigs to opacify the gallbladder. Under fluoroscopy, the opacified gallbladder was punctured percutaneously and three suture anchors were used to fix the anterior wall of the gallbladder to the abdominal wall. Two weeks later, the gallbladder was punctured and access into the distal common bile was obtained through the cystic duct. Balloon expandable stents were deployed into the distal common bile duct. Follow-up cholangiograms were obtained at 1 and 2 weeks. Necropsy was performed after 2 weeks to evaluate the relationship between the gallbladder and abdominal wall. Suture anchor placement was successful in all five pigs. One pig with a deep and highly positioned gallbladder developed fever, anorexia, and vomiting secondary to excessive stretch of the gallbladder. Placement of the guidewire through the extremely tortuous and small cystic ducts proved to be the most challenging step of the procedure. Metallic stents were successfully deployed in all four pigs in which it was attempted. Four animals tolerated the procedures without changes in their clinical conditions and no symptoms. Successful follow-up cholangiograms were performed at 1 and 2 weeks post-stent deployment without complications. All stents remained patent during the follow-up period. Necropsy demonstrated close attachment and adherence of the gallbladders to the antero-lateral abdominal wall in all four animals. Suture anchoring of the gallbladder is feasible in most pigs with superficially located gallbladders. This technique allows a safe and repeat access into the biliary system using a transcholecystic approach

    Full Text Available During the last decade, pediatric nonalcoholic liver disease has reached epidemic proportions, becoming one of the most frequent chronic liver diseases in the global child population. Purpose: to study the relationship of the functional state of the gallbladder with structural changes in the liver in children with nonalcoholic fatty liver disease. Materials and methods. We examined 34 children aged from 8 to 17 years old. Hepatic steatosis was determined using the FibroScan® 502 touch with controlled attenuation parameter (CAP. According to the results of transient elastometry and ultrasound of the abdomen with the gallbladder function study, patients were divided into 4 groups: the 1st group consisted of 7 patients with steatosis and hypofunction of gallbladder (20.5 %, group 2 included 6 patients with steatosis and gallbladder normofunction (17.65 %, group 3 consisted of 11 patients without hepatic steatosis with hypofunction of gallbladder (32.35 %, group 4 included 10 patients without hepatic steatosis with gallbladder normofunction (29.4 %. Results. The sonographic studies demonstrated children of the 1st group (steatosis with gallbladder hypokinesia to have significantly larger sizes of liver lobes compared to group 4 (children without steatosis with gallbladder normofunction. Also, the stiffness of the liver parenchyma was highest in patients with hepatic steatosis and gallbladder hypokinesia. Discussion. The combination of hepatic steatosis and hypokinesia of the gallbladder in children is accompanied by a significant increase in liver size, increased stiffness of the liver parenchyma and increasing degree of steatosis. The data indicate the relationship of the gallbladder function and the liver structural changes.

    Submucosal tunneling endoscopic resection (STER) has been proved to be safe and effective for removal of esophageal leiomyoma originating from the muscularis propria (MP) layer. However, there are still technical challenges for tumors ≥35 mm due to the limited space of the submucosal tunnel. The aim of the study was to estimate the safety and efficacy of STER for large esophageal leiomyoma originating from the MP layer as well as compare its efficacy with video-assisted thoracoscopic surgery (VATS), which is a standard procedure for treating esophageal leiomyoma. We retrospectively collected the clinical data of the patients with esophageal leiomyoma of 35-55 mm who underwent STER or VATS at our hospital between January 2010 and December 2014. Epidemiological data (gender, age), tumor location, tumor size, procedure-related parameters, complications, length of stay and cost were compared between STER and VATS. A total of 31 patients were enrolled, and 18 patients underwent STER and the other 13 received VATS. There was no significant difference between the two groups in gender, age, tumor location, tumor size, complications and rate of en bloc resection (P > 0.05). However, patients in the STER groups had a shorter operation time, a less decrease in hemoglobin level, a shorter length of hospital stay and a decreased cost (P leiomyoma of 35-55 mm. However, STER is superior to VATS in a shorter operation time, a less decrease in hemoglobin level, a shorter length of hospital stay and a decreased cost.

    Gallbladder carcinoma is the most common biliary tract tumor and the fifth most common gastrointestinal tract cancer .The prognosis of gallbladder carcinoma is poor and less than 5% of the patients are still alive five years postoperatively. Gallbladder specimens were obtained during surgical operations performed in eleven patients for resection of a gallbladder carcinoma, and during five autopsies (control cases selected among patients who died from for other causes, excluding those suffering from biliary or hepatic diseases). Immunohistochemical characterization and distribution of neurotrophins, with their respective receptors, were analyzed. The actual role played by these neurotrophic factors in the general regulation, vascular permeability, algic responsiveness, release of locally active substances and potential tumorigenesis in the gallbladder and biliary ducts compartment remains controversial. Our study revealed an increased immunohistochemical expression of NGF and TrKA in the epithelium and in the epithelial glands of the gallbladder carcinoma together with an evident immunoreactivity for BDNF in the same neoplastic areas. An evident immunoreactivity for NGF, TrKA and BDNF was observed in control specimens of gallbladder obtained during autopsies, whereas a weak or quite absent immunoreactivity was observed in the same specimens for NT4, TrKC and p75. On the contrary an appreciable immunoreactivity for p75 was observed in the specimens harvested from patients with gallbladder carcinoma. We also investigated the expression of some known tumor markers such as MIB-1 (anti Ki-67), CD34 and CA15-3, to identify a possible correlation between the expression of these molecular factors and the prognosis of gallbladder carcinoma. They resulted highly expressed in the stroma (CD34 and CA 15-3) and in the epithelium/epithelial glands (MIB-1) of the neoplastic areas and appeared to be almost absent in the control cases, suggesting that these markers, taken together

    The hormone leptin is produced by mature adipocytes and plays an important role in regulating food intake and energy metabolism through its interaction with the leptin receptor. In addition to roles in obesity and obesity-related diseases, leptin has been reported to affect the components and secretion of bile in leptin-deficient mice. Furthermore, gallbladder diseases such as cholelithiasis are known to be associated with serum leptin concentrations in humans. We hypothesized that the canine gallbladder is a source of leptin and that the leptin receptor may be localized in the gallbladder, where it plays a role in regulating the function of this organ. The aim of this study was to demonstrate the presence and expression patterns of leptin and its receptors in normal canine gallbladders using reverse transcriptase-PCR (RT-PCR) and immunohistochemistry. Clinically normal gallbladder tissue samples were obtained from four healthy beagle dogs with similar body condition scores. RT-PCR and sequencing of the amplified PCR products revealed the presence of leptin mRNA and its receptors in the gallbladder. Immunohistochemical investigations demonstrated the expression of leptin and its receptors in the luminal single columnar and tubuloalveolar glandular epithelial cells. In conclusion, the results of this study demonstrated the presence of leptin and its receptors in the gallbladders of dogs. Leptin and its receptor were both localized throughout the cytoplasm of luminal and glandular epithelial cells. These results suggested that the gallbladder is not only a source of leptin, but also a target of leptin though autocrine/paracrine mechanisms. The results of this study could increase the understanding of both the normal physiological functions of the gallbladder and the pathophysiological mechanisms of gallbladder diseases characterized by leptin system dysfunction.

    Purpose: To analyze the effect of adjuvant chemoradiotherapy on gallbladder carcinoma. Methods and Materials: We retrospectively reviewed the records from consecutive patients who underwent R0 resection of gallbladder carcinoma between January 1, 1985, and December 31, 2004. Patients had either Stage I (T1-T2N0M0) or Stage II (T3N0M0 or T1-T3N1M0) disease. Patients undergoing adjuvant therapy received 5-fluorouracil chemotherapy concurrently with radiotherapy (median dosage, 50.4 Gy in 28 fractions). Adverse prognostic factors and the effect of adjuvant treatment on overall survival (OS) were evaluated. Results: A total of 73 patients were included in the analysis; of these, 25 received adjuvant chemoradiotherapy. On univariate analysis, no adverse prognostic factors for OS reached statistical significance, but trends were noted for Stage N1 vs. N0 (p = .06), Nx vs. N0 (p = .09), Stage T3 vs. T1-T2 (p = .06), and histologic findings other than adenocarcinoma (p = .13). The median OS for patients receiving adjuvant chemoradiotherapy vs. surgery alone was 4.8 years and 4.2 years, respectively (log-rank test, p = .56). However, a significantly greater percentage of patients receiving adjuvant chemoradiotherapy had Stage II disease (p <.001). In the multivariate Cox model, increasing T and N category and histologic findings other than adenocarcinoma were significant predictors of decreased OS. Additionally, adjuvant chemoradiotherapy was a significant predictor of improved OS after adjusting for these prognostic factors (hazard ratio for death, 0.3; 95% confidence interval, 0.13-0.69; p = .004). Conclusion: After adjusting for the stage parameters and histologic findings, our data suggest that adjuvant chemoradiotherapy might improve OS for patients with gallbladder cancer.

    Liver biopsy is a common procedure, with an inherent risk of bleeding. There are different ways to help avoid hemorrhage, including biopsy through a transjugular venous route or embolization of the tract with liquid or solid materials. We describe an image-guided percutaneous core needle liver biopsy with tract embolization using thick Gelfoam slurry in a pediatric oncology patient. Imaging studies acquired after the biopsy indicated that the Gelfoam mixture had likely migrated to the gallbladder and common bile duct. We report this rare occurrence with its striking imaging in order to make those performing biopsies aware of this possibility. (orig.)

    Endoscopic sphincterotomy (ES) with extraction of calculi is a basic method of treating choledocholithiasis in post-cholecystectomy patients (8, 9). Endoscopic treatment contributes to a considerable reduction of the indications for reoperation. The existing views concerning ES done in patients with preserved gallbladder, especially in the era of laparoscopic surgery, are still conflicting (3, 6). There are several options: cholecystectomy with removal of calculi in the common bile duct by ES in a subsequent stage, or vice versa-primary ES with ensuring cholecystectomy. The undertaking of independent surgical or endoscopic treatment is likewise practicable (2, 6).

    In order to study prostaglandin release from guinea pig gallbladder, full thickness tissue sections were incubated for one hour in Krebs solution. Extraction and two dimensional chromatography of incubation media obtained in the presence of radio-labelled arachidonic acid demonstrated the presence of PGE2, PGF2 alpha, 6-keto-PGF1 alpha and thromboxane B2. These results were supported by radioimmunoassay of incubations conducted in the absence of exogenous arachidonate and in the presence of varying concentrations of unlabelled exogenous arachidonate. The previously reported predominance of PGE2 was only seen at high concentrations of exogenous arachidonate.

    Full Text Available Abstract Background The objective of this study was to examine the extent of surgical procedures, pathological findings, complications and outcome of patients treated in the last 12 years for gallbladder cancer. Methods The impact of a standardized more aggressive approach compared with historical controls of our center with an individual approach was examined. Of 53 patients, 21 underwent resection for cure and 32 for palliation. Results Overall hospital mortality was 9% and procedure related mortality was 4%. The standardized approach in UICC stage IIa, IIb and III led to a significantly improved outcome compared to patients with an individual approach (Median survival: 14 vs. 7 months, mean+/-SEM: 26+/-7 vs. 17+/-5 months, p = 0.014. The main differences between the standardized and the individual approach were anatomical vs. atypical liver resection, performance of systematic lymph dissection of the hepaticoduodenal ligament and the resection of the common bile duct. Conclusion Anatomical liver resection, proof for bile duct infiltration and, in case of tumor invasion, radical resection and lymph dissection of the hepaticoduodenal ligament are essential to improve outcome of locally advanced gallbladder cancer.

    The quality of the archival samples stored at pathology services could be a limiting factor for molecular biology studies. To determine the quality of DNA extracted from gallbladder cancer samples at different institutions. One hundred ninety four samples coming from five medical centers in Chile, were analyzed. DNA extraction was quantified determining genomic DNA concentration. The integrity of DNA was determined by polymerase chain reaction amplification of different length fragments of a constitutive gene (β-globin products of 110, 268 and 501 base pairs). The mean DNA concentration obtained in 194 gallbladder cancer samples was 48 ± 43.1 ng/µl. In 22% of samples, no amplification was achieved despite obtaining a mean DNA concentration of 58.3 ng/ul. In 81, 67 and 22% of samples, a DNA amplification of at least 110, 268 or 501 base pairs was obtained, respectively. No differences in DNA concentration according to the source of the samples were demonstrated. However, there were marked differences in DNA integrity among participating centers. Samples from public hospitals were of lower quality than those from private clinics. Despite some limitations, in 80% of cases, the integrity of DNA in archival samples from pathology services in our country would allow the use of molecular biology techniques.

    Full text: Our purpose was to evaluate the gallbladder (GB) emptying in pts with chronic pancreatitis and to determine whether or not the use of pancreatic extract has an impact in improving that function. The GB emptying was evaluated in 11 patients (pts) with mild to moderate chronic pancreatitis, and in 10 normal volunteers. Pts and controls who presented any kind of condition that could interfere with the gastric or gallbladder emptying were excluded. The GB ejection fraction was calculated at 30, 45, and 60 minutes after a standardized fatty meal ingestion. In the pts group, this evaluation was obtained in two different periods of time, without and with the addition of pancreatic extract. The gastric emptying was previously determined in all patients and controls with Technetium-99m-sulfur colloid mixed in the same fatty meal used for the hepatobiliary scans. The results disclosed that the GB ejection fraction at 60 minutes was significantly lower in patients compared to controls ( 0,05). The gastric emptying was similar between the two groups (p>0,05). In conclusion, mild to moderate chronic pancreatitis is associated with GB function impairment. Our results suggest that the delay in GB emptying does not depend exclusively on the alteration in the intestinal phase of the GB stimulation, but may be a result of multiple other factors

    To evaluate a newly developed cholecystectomy technique which combines classical dissection with currently available mini-instrumentation (3 and 5 mm) and removal of the gallbladder through a short gastrotomy. After a feasibility study, we set up a protocol for this procedure using instrumentation currently available on the market. The resected gallbladder was removed through a short gastrotomy on the anterior gastric wall, thereby minimizing abdominal wall trauma and permitting the patient to resume physical activity more quickly with no risk of trocar herniation. Cholecystectomy was performed by the described technique in 18 of 23 eligible patients between April 2008 and August 2008. There were seven males and 11 females with a mean age of 48 (range: 28-77); median BMI was 30 kg/m2 (range: 22-36). Eleven patients had a gallstone larger than 12 mm. There were no postoperative complications and recovery was rapid for all patients in our study. This procedure is technically feasible, safe and reproducible; results are good with minimal trauma to the abdominal wall. Normal physical activity can be rapidly resumed with no risk of incisional hernia.

    The aim of this study was to correlate MR findings of gallbladder wall thickening with pathologic findings on the basis of the layered pattern and to evaluate the diagnostic value of MR imaging in gallbladder disease. We retrospectively evaluated the source images of HASTE sequences for MR cholangiography in 144 patients with gallbladder wall thickening. The layered pattern of thickened wall was classified into four patterns. Type 1 shows two layers with a thin hypointense inner layer and thick hyperintense outer layer. Type 2 has two layers of ill-defined margin. Type 3 shows multiple hyperintense cystic spaces in the wall. Type 4 shows diffuse nodular thickening without layering. MR findings of a layered pattern of thickened gallbladder were well correlated with histopathology. Chronic cholecystitis matched to type 1, acute cholecystitis corresponded to type 2, adenomyomatosis showed type 3, and the gallbladder carcinomas showed type 4. All four layered patterns were associated with PPV of 73% or greater, sensitivity of 92% or greater and specificity of 95% or greater. Our results indicate that MR findings of gallbladder wall thickening are characteristic in each entity and correlate well with pathologic findings. The classification of the layered pattern may be valuable for interpreting thickened gallbladder wall. (orig.)

    Sixty-three patients with the clinical suspicion of acute cholecystitis were examined with infusion tomography of the gallbladder. Ultrasonography was performed in 51 of these cases. The technique and diagnostic principles of both methods are discussed. The diagnostic value of the two methods when used in combination is stressed. Thus in a case of gangrenous cholecystitis when opacification of the gallbladder wall may not appear at infusion tomography, ultrasonography may demonstrate signs of gallbladder disease. Infusion tomography, on the other hand, may be of great value if ultrasonography is not informative. (orig.) 891 AJ/orig. 892 BRE [de

    Laparoscopic cholecystectomy has become a standardized technique within the last years. However, the extraction of the stone-filled gallbladder often becomes a time-consuming and difficult part of the operation. We have developed a new instrument for quick and safe extraction of the stone-filled gallbladder. The instrument, called "Bergetrokar", is a trocar cannula with a trumpet valve and cone-shaped tip which can be spread. The application of this device is simple. After using the "Bergetrokar" in about 180 cases we have not observed any perforation of the gallbladder or loss of stones. Extraction times were reduced.

    Ceftriaxone, a third-generation cephalosporin, is partially excreted into bile. With its clinical use, the formation of gallbladder sludge detected by ultrasonography has been reported. Four surgical specimens were examined and no gallstones were found. Instead, fine precipitates of 20-250 microns were present. Microscopically, there was a small number of cholesterol monohydrate crystals and bilirubin granules among an abundant amount of granular-crystalline material that was not morphologically cholesterol monohydrate crystals. The chemical composition of the precipitates (n = 4) was determined. There was a small amount of cholesterol (1.7% +/- 0.8%) and bilirubin (13.9% +/- 0.74%). The major component of the precipitate was a residue. On further analysis using thin-layer chromatography, high-performance liquid chromatography, and electron microprobe analysis, the residue was identified as a calcium salt of ceftriaxone. The residue also had identical crystal morphology and chromatographic elution profile as authentic calcium-ceftriaxone standards. It is concluded that ceftriaxone, after excretion and being concentrated in the gallbladder bile, can form a precipitate. The major constituent has been identified as a ceftriaxone-calcium salt

    Systemic vasculitis (SV) involving abdominal structures usually has a poor prognosis. Gallbladder vasculitis (GV) has been reported as part of SV (GB-SV) and focal single-organ vasculitis (GB-SOV). We analyzed clinical and histologic characteristics of patients with GV to identify features that differentiate GB-SOV from the systemic forms of GV. To identify affected patients with GV we used pathology databases from our institution and an English-language PubMed search. Clinical manifestations, laboratory and histologic features, treatment administered, and outcomes were recorded. Patients were divided in 2 groups, GB-SOV and GB-SV. As in previous studies of single-organ vasculitis, GB-SOV was only considered to be a sustainable diagnosis if disease beyond the gallbladder was not apparent after a follow-up period of at least 6 months. Sixty-one well-characterized patients with GV were included (6 from our institution). There was no significant sex bias (32 female patients, 29 male). Median age was 52 years (range, 18-94 yr). GB-SOV was found in 20 (33%) and GB-SV in 41 (67%) patients. No differences were observed in age, sex frequency, or duration of gallbladder symptoms between groups. Past episodes of recurrent right-upper quadrant or abdominal pain and lithiasic cholecystitis were more frequent in GB-SOV patients, whereas acalculous cholecystitis occurred more often in GB-SV. In GB-SV, gallbladder-related symptoms occurred more often concomitantly with or after the systemic features, but they sometimes appeared before SV was fully developed (13.5%). Constitutional and musculoskeletal symptoms were reported only in GB-SV patients. Compared to GB-SOV, GB-SV patients presented more often with fever (62.5% vs 20%; p = 0.003) and exhibited higher erythrocyte sedimentation rate levels (80 ± 28 vs 37 ± 25 mm/h, respectively; p = 0.006). All GB-SV patients required glucocorticoids and 50% of them also received cytotoxic agents. Mortality in GB-SV was

    Full Text Available Radiofrequency ablation (RFA is an effective minimally invasive treatment for nonsurgical hepatocellular carcinoma (HCC, but ablation of tumors close to the gallbladder could be associated with several complications. We report our experience on the treatment of HCC close to the gallbladder with RFA. Eight RFA procedures were performed in eight patients with HCC larger than 3 cm and less than 5 cm close to the gallbladder. In all cases, a percutaneous approach was used. There were no major complications. Only in two patients a minimal wall thickening of the gallbladder was observed. Contrast enhanced computed tomography carried out after 30 days from the first procedure showed complete necrosis in seven patients (87%. Only one patient had local recurrence at 11 months of followup. Although limited, our experience suggests that, after careful preprocedural planning, in experienced hands and with appropriate technology, percutaneous RFA could be safely performed even for lesions larger than 3 cm located in close adjacency to the gallbladder.

    To establish the optimal inclusion criteria for the patients with gallbladder stones to extracorporeal shock wave lithotripsy(ESWL) by retrospectively analyzed our current results. Data obtained from 201 patients with gallbladder stones treated with ESWL and oral chemolytic agent from November 1988 to July 1992 were retrospectively analyzed. Ninety-six had radiolucent stones and 105 had radiopaque stones. We used piezoelectric lithotriptor(EDAP LT. 01) and there were no limitation in number of sessions or total number of shock waves. ESWL was repeated until the size of the largest fragment is smaller than 4 mm. Follow up ultrasound was done in every three months after the successful fragmentation. Average length of the follow up was 205 days. We analyzed the rate of successful fragmentation, number of shock waves needed to achieve successful fragmentation according to the size, number of stones as well as the presence of the calcification. Stone-free rate after 6 months was also calculated from all subgroups and compared to each other. The rate of successful fragmentation was 76.2% for radiolucent stones and 65.6% for radiopaque stones(p> 0.05) after 46,731 and 56,111 shock wave respectively(p > 0.05) The rate of successful fragmentation was highest in patients with single, radiolucent stone smaller than 2 cm(91.7%) followed by single radiolucent stone larger than 2 cm(83.3%), multiple calcified stones smaller than 2 cm (77.4%) and single calcified stone smaller than 2 cm(72.1%). The rate of complete stone clearance after 6 month follow-up was highest in patients with single radiolucent stone smaller than 2 cm (63.3%) and followed by multiple calcified stones smaller than 2 cm(37.3%), single calcified stone smaller than 2 cm(33.9%)(p < 0.05). To obtain better results with ESWL in patients with gallbladder stone, the authors propose a more strict inclusion criteria, which is the patient with a single, radiolucent stone smaller than 2 cm.

    Objective: To investigate gallbladder function in patients with spinal cord injury (SCI). Methods: Eighteen normal control subjects, 16 other traumatic control subjects and 46 SCI patients were include. Gallbladder function was quantitatively evaluated by 99 Tc m labeled imino-diacetic acid analogue (DISIDA) hepatobiliary imaging using two parameters as filling fraction (FF) and ejection fraction (EF). The gallbladder function of SCI patients was further analyzed according to age, sex, body weight, injury gradient (with ASIA criteria), cord injury level and the duration of injury. Results: 52% of SCI patients had abnormal FF and 59% with abnormal EF. Significantly decreased FF and EF values were found in SCI patients, especially in those who were female, severe and high-level injuries of spinal cord. Conclusion: With the use of quantitative 99 Tc m -DISIDA hepatobiliary imaging, significant impairment of the gallbladder function was found in SCI patients. (authors)

    A potentially serious complication of laparoscopic cholecystectomy is the inadvertent dissemination of unsuspected gallbladder carcinoma. There are increasing reports of seeding of tumor at the trocar sites following laparoscopic cholecystectomy in patients with unexpected or inapparent gallbladder carcinoma. Although the mechanism of the abdominal wall recurrence is still unclear, laparoscopic handling of the tumor, perforation of the gallbladder, and extraction of the specimen without an endobag may be risk factors for the spreading of malignant cells. The Authors report the case of late development of umbilical metastasis after laparoscopic cholecystectomy; the presence of an incisional hernia and the finding of a stone in subcutaneous tissue demonstrate the diffusion of tumor cells into subcutaneous tissue during the extraction of gallbladder. The patient underwent an excision of the metastases. She is disease free two years after surgical treatment.

    A 68-year-old female with colorectal cancer developed a metachronous isolated fluorodeoxyglucose-avid (FDG-avid) segment 5/6 gallbladder fossa hepatic lesion and was referred for percutaneous ablation. Pre-procedure computed tomography (CT) images demonstrated a distended gallbladder abutting the segment 5/6 hepatic metastasis. In order to perform ablation with clear margins and avoid direct puncture and aspiration of the gallbladder, cholecystokinin was administered intravenously to stimulate gallbladder contraction before hydrodissection. Subsequently, the lesion was ablated successfully with sufficient margins, of greater than 1.0 cm, using microwave with ultrasound and FDG PET/CT guidance. The patient tolerated the procedure very well and was discharged home the next day.

    This paper assesses the value and outcome of combined surgical (mini-cholecystostomy) and radiologic stone extraction in high-risk patients with acute calculous gallbladder disease. Sixty-seven patients were treated over a 6-year period. Three were 37 women and 30 men (age range, 33-98 years; mean, 73 years). Fifty (74%) surgical procedures were performed under local anesthesia. Radiologic gallstone extraction was achieved in 49 patients (73%). Extra-corporeal shock wave lithotripsy was required in six patients to fragment large stones. Twelve patients (18%) also had bile duct stones, of which 8 (67%) were successfully cleared. There were 4 deaths (6%) within 30 days. Twelve cholecystectomies (18%) were performed between 3 and 19 weeks (mean, 9 weeks) after minicholecystostomy as a result of failed stone clearance. The long-term outcome for those patients whose gallstones were cleared are discussed

    Full Text Available Hepatic infarction is known as a rare disease entity in nontransplant patients. Although a few cases of hepatic infarction have been reported to be linked with invasive procedures, trauma, and hypercoagulability, a case of spontaneous hepatic infarction in a nontransplanted patient has hardly ever been reported. However, many clinical situations of patients with cancer, in particular biliary cancer, can predispose nontransplant patients to hepatic infarction. Besides, the clinical outcome of hepatic infarction in patients with cancer can be worse than in patients with other etiologies. As for treatment, anticoagulation treatment is usually recommended. However, because of its multifactorial etiology and combined complications, treatment of hepatic infarction is difficult and not simple. Herein, we report a case of fatal hepatic infarction that occurred spontaneously during the course of treatment in a patient with gallbladder cancer. Hepatic infarction should be considered as a possible fatal complication in patients during treatment of biliary malignancies.

    Full Text Available Aim. We examined the effectiveness of bile juice cytology for distinguishing between benign and malignant gallbladder lesions of the protruding type with various sampling points, sampling methods, and macroscopic forms in order to discuss the effectiveness of the endoscopic transpapillary gallbladder drainage (ETGD cytology. Methods. We studied 162 cases of patients with a lesion localized within the gallbladder. At first, we examined the effectiveness for diagnosis of ETBD cytology using ERC and then that of the first ETGD cytology after placing the ETGD. Next, we examined the diagnostic effectiveness of the washed ETGD cytology by using the ETGD. Finally, we examined complications. Results. In the final diagnoses, we identified 33 cases of adenocarcinoma, 10 cases of adenoma, 63 cases of ADM, 35 cases of nonneoplastic polyp, and 21 cases of chronic cholecystitis. It was found that the sensitivity of ETBD cytology was 3.6% and that of ETGD cytology was 59.1%. In the comparison of diagnostic effectiveness of cytologic diagnosis using samples of bile juice from the gallbladder collected by different methods, the sensitivities were 38.9% and 73.3% for the first and washed ETGD cytologies, respectively. In the comparison of the diagnostic effectiveness of gallbladder bile juice cytology using samples collected for different forms of lesion and by different methods, the sensitivities were 38.9% and 73.3%, respectively, for the first and washed ETGD cytologies for flat gallbladder wall thickening, while it was impossible to diagnose for lesions of GB polyp. Conclusion. For diagnosis of gallbladder cancer, we consider that the ETGD cytology should be taken into consideration for lesions of flat gallbladder wall thickening, for which it is difficult to distinguish between benign and malignant lesions.

    However, technical advances in ultrasono imaging have had a remarkable impact on the study of biliary system oral cholecystography is a contrast of the gallbladder which is very frequently performed even with the application of Extra Shock Wave Lithotripsy(ESWL) in clinical use. Oral GB requires a stringent preparation if it is to be fully successful and a considerable amount of time to complete all its procedures and its objects of the radiographs. 1) to obtain a firm diagnosis of the presence of gallstones. 2) to ease function of the gallbladder that is, its ability to concentrate and store bile After a times sequence of X - ray exposures taken in various positions to show the gallbladder to be satisfactorily filled, the patient is given a fatty meal, for instances two eggs or a cup of milk. The gallbladder which is drained by the cystic duct stores and concentrates the bile and is stimulated to contrast and excrete the bile by hormone 'cholecystokinin' secreted in the intestinal mucosa. To evaluate the effect of the fatty meal which caused the gallbladder to constrict and empty, and by so doing the contrast medium passes through the cystic and bile ducts which are shown in radiographs exposed from 15-30 minutes after the variety practice of fatty meal, such as soft-boiled 2 eggs, raw 2 eggs, 100g of peanuts, and 200ml of milk. If the concentration of the opaque medium in the gallbladder is adequate, then not only the size, shape and position of the gallbladder will be shown from firms taken at intervals, the rate of concentration of the opaque medium and of the emptying of gallbladder has been measured and analyzed

    Background: Laparoscopic common bile duct exploration (LCBDE) for stone can be carried out by either laparoscopic transcystic stone extraction (LTSE) or laparoscopic choledochotomy (LC). It remains unknown as to which approach is optimal for management of gallbladder stone with common bile duct stones (CBDS) in Chinese patients. Methods: From May 2000 to February 2009, we prospective treated 346 consecutive patients with gallbladder stones and CBDS with laparoscopic cholecystectomy and LCBDE....

    Bacterial cholecystitis often is diagnosed by combination of gallbladder ultrasound (US) findings and positive results of bile culture. The value of gallbladder US in determining the likelihood of bile bacterial infection in cats and dogs with suspected biliary disease is unknown. To determine the value of gallbladder US in predicting bile bacterial culture results, identify most common bacterial isolates from bile, and describe complications after cholecystocentesis in cats and dogs with suspected hepatobiliary disease. Cats (70) and dogs (202) that underwent an abdominal US and submission of bile for culture were included in the study. A cross-sectional study design was used to determine the association of gallbladder US abnormalities and the results of bile cultures, and complications of cholecystocentesis. Abnormal gallbladder US had high sensitivity (96%) but low specificity (49%) in cats with positive and negative results of bile bacterial culture, respectively. Cats with normal gallbladder US findings were unlikely to have positive bile bacterial culture (negative predictive value of 96%). Gallbladder US had lower sensitivity (81%), specificity (31%), positive predictive value (20%), and negative predictive value (88%) in dogs. The most common bacterial isolates were of enteric origin, the prevalence being higher in cats. Incidence of complications after cholecystocentesis was 3.4%. Gallbladder US has a high negative predictive value for bile culture results in cats. This modality is less predictive of infection in dogs. Percutaneous US-guided cholecystocentesis has a low complication rate. Copyright © 2017 The Authors.

    However, technical advances in ultrasono imaging have had a remarkable impact on the study of biliary system oral cholecystography is a contrast of the gallbladder which is very frequently performed even with the application of Extra Shock Wave Lithotripsy(ESWL) in clinical use. Oral GB requires a stringent preparation if it is to be fully successful and a considerable amount of time to complete all its procedures and its objects of the radiographs. 1) to obtain a firm diagnosis of the presence of gallstones. 2) to ease function of the gallbladder that is, its ability to concentrate and store bile After a times sequence of X - ray exposures taken in various positions to show the gallbladder to be satisfactorily filled, the patient is given a fatty meal, for instances two eggs or a cup of milk. The gallbladder which is drained by the cystic duct stores and concentrates the bile and is stimulated to contrast and excrete the bile by hormone 'cholecystokinin' secreted in the intestinal mucosa. To evaluate the effect of the fatty meal which caused the gallbladder to constrict and empty, and by so doing the contrast medium passes through the cystic and bile ducts which are shown in radiographs exposed from 15-30 minutes after the variety practice of fatty meal, such as soft-boiled 2 eggs, raw 2 eggs, 100g of peanuts, and 200ml of milk. If the concentration of the opaque medium in the gallbladder is adequate, then not only the size, shape and position of the gallbladder will be shown from firms taken at intervals, the rate of concentration of the opaque medium and of the emptying of gallbladder has been measured and analyzed.

    There are conflicting data in the literature regarding the reproducibility of the gallbladder ejection fraction (GBEF) measured by fatty meal cholescintigraphy (CS). We aimed to test the reproducibility of GBEF measured by fatty meal CS. Thirty-five subjects (25 healthy volunteers and 10 patients with chronic abdominal pain) underwent fatty meal CS twice in order to measure GBEF1 and GBEF2. The healthy volunteers underwent a repeat scan within 1-13 months from the first scan. The patients underwent a repeat scan within 1-4 years from the first scan and were not found to have chronic acalculous cholecystitis (CAC). Our standard fatty meal was composed of a 60-g Snickers chocolate bar and 200 ml full-fat yogurt. The mean ± SD values for GBEF1 and GBEF2 were 52±17% and 52±16%, respectively. There was a direct linear correlation between the values of GBEF1 and GBEF2 for the subjects, with a correlation coefficient of 0.509 (p=0.002). Subgroup data analysis of the volunteer group showed that there was significant linear correlation between volunteer values of GBEF1 and GBEF2, with a correlation coefficient of 0.473 (p=0.017). Subgroup data analysis of the non-CAC patient group showed no significant correlation between patient values of GBEF1 and GBEF2, likely due to limited sample size. This study showed that fatty meal CS is a reliable test in gallbladder motility evaluation and that GBEF measured by fatty meal CS is reproducible

    The changes of cancer incidence upon immigration can be used as an estimator of environmental influence on cancer risk. We studied site-specific liver and biliary cancers in first-generation immigrants to Sweden with an aim to search for aetiological clues and to find evidence for indigenous incidence rates. We used the nation-wide Swedish Family-Cancer Database to calculate standardised incidence ratios (SIRs) in immigrants compared to native Swedes. A total of 1428 cancers were identified in immigrants whose median ages (years) at immigration were 27 for men and 26 for women and whose median diagnostic ages were 64 and 66, respectively. The highest SIRs of 6.7 for primary liver cancer were observed for men from East Asia and sub-Saharan Africa. Increased SIRs were recorded for male immigrants from previous Yugoslavia (1.78), Southern Europe (2.91), Turkey (2.15) and Asian Arab countries (2.89). For gallbladder cancer, only women from the Indian subcontinent (3.84) and Chile (2.34) had increased risk while some Northern European immigrants showed decreased risks. Primary liver cancer was increased in immigrants from endemic regions of hepatitis B virus infection but also from large regions lacking cancer incidence data, North Africa, Asian Arab countries, Turkey and previous Yugoslavia; these are probably intermediary risk regions for this infection. The consideration of these regions as risk areas would justify active diagnostic and vaccination programs. The increase in gallbladder cancer in Chileans and Indians suggests that some persistent damage was inflicted before emigration, characterisation of which will be a challenge for aetiological studies.

    Full Text Available The factors enhancing mucocoele development in dogs remain poorly understood. A 7-year-old female spayed Miniature Schnauzer was presented to the Massey University Veterinary Teaching Hospital for progressive lethargy, inappetance and abdominal discomfort. Initial physical examination findings revealed a moderate degree of cranial abdominal pain, with subsequent diagnostic tests confirming the patient as having diabetes mellitus, with a concurrent marked hypertriglyceridaemia. In an attempt to localise the source of pain, an ultrasound examination of the abdomen was performed, revealing a marked degree of gallbladder sludge. With appropriate medical management including ursodeoxycholic acid and insulin therapy, the patient stabilised and was discharged. With persistence of clinical signs three months later, progression of the gallbladder sludge towards mucocoele development was suspected. Exploratory laparotomy was instigated, and an emergency cholecystectomy was performed. This case report therefore entails a suspected gallbladder mucocoele that developed in a diabetic patient with previously diagnosed biliary sludge. A unique feature of this case report is the presence of diabetes mellitus, which has been suggested to be a causative factor in the development of gallbladder mucocoeles. It is also hypothesised that gallbladder sludge and mucocoeles are associated, however it is yet to be ascertained whether this association is causal or contributory. The authors examined the possible relationship between this endocrinopathy and biliary sludge, and their possible effects on mucocoele development. Specific associated factors to sludge formation are also examined. The medical and surgical management of gallbladder mucocoeles is discussed.

    Clear cell gallbladder carcinoma accounts for less than 1% of all gallbladder malignancies and demonstrates its unique histopathological characteristics in patients with no prior medical illness or familial predisposition. Here we present a case of a 56-year-old female, with no prior medical conditions presented with a 2-month history of upper abdominal pain. Routine hematological and biochemical tests were unremarkable. An abdominal ultrasound revealed the presence of a gallbladder calculi, and a fundic mass while magnetic resonance cholangiopancreatography revealed a 8.0cm×3.5cm gallbladder mass. Computed tomography imaging excluded any distant haematogenous metastases. An open cholecystectomy with lymphadenectomy was proceeded by staging laparoscopy. Upon pathologic investigation, the morphologic and immunophenotypic features supported a diagnosis of clear cell variant of gallbladder carcinoma. Pathological prognostications for primary clear cell gall bladder carcinomas are not well defined due to the rarity of cases and possible misidentification as secondary metastases. Foci of adenocarcinoma within the tumor along with immunohistochemical staining probes can be informative in consideration of differential diagnosis. In these cases, clinical case management should be personalized for increased survival with the possible incorporation of next generation sequencing approaches to guide therapeutic algorithms. We discuss this exceedingly rare case of the clear cell variant of gallbladder carcinoma in detail, highlighting some of the diagnostic, and clinical challenges. Copyright © 2017 The Authors.

    Gastrin and cholecystokinin (CCK) receptors are trophic for various gastrointestinal malignancies. Their role in gallbladder cancer has not been widely studied. To identify expression of CCK-A and CCK-B receptors in the tissue and blood of patients suffering from carcinoma (CA) gallbladder and gallstone disease and to compare expression of CCK A and B receptors in the gall bladder tissue and blood of healthy individuals and patients of CA gallbladder, and gallstone diseases. Forty nine subjects of both genders were recruited, comprising of 22 patients of CA gall bladder, 19 cases of cholelithiasis and, 8 normal gallbladders obtained from patients operated for trauma of the biliary system or Whipple's procedure. RNA extraction and cDNA formation for CCK-A and CCK-B receptors were carried out. Real Time PCR was performed on cDNA and threshold cycle (Ct) value of each sample was obtained and ΔCt was calculated. Chi-square test for comparing two groups and ANOVA test for comparing multiple groups were applied and if pgallbladder and there was no difference among them (p>0.05). This preliminary study showed higher expression of CCK-A receptors in patients of cholelithiasis and decreased expression of CCK-A receptors in patients of CA gallbladder as compared to normal gallbladder although it did not rise to statistical significance.

    An 86-year-old man was admitted to our department with complaints of intermittent upper abdominal pain. Ultrasonography of the abdomen showed dilated extrahepatic bile ducts containing stones; however, the gallbladder was not clearly identified. Magnetic resonance cholangiopancreatography showed dilated extrahepatic ducts and choledocholithiasis without gallbladder visualization. The stone extraction was performed with endoscopic sphincterotomy. Three-dimensional images using spiral-computed tomography after intravenous-infusion cholangiography clearly demonstrated an obstruction of the cystic duct. The patient was scheduled for laparoscopic cholecystectomy. At laparoscopy, the gallbladder fossa was not identified on the undersurface of the liver. Despite a thorough examination of the intrahepatic (left-sided within the lesser omentum), retroperitoneal, retrohepatic (within the falciform ligament), retroduodenal, and retropancreatic areas using laparoscopic ultrasonography, the gallbladder was not found. After careful dissection of the hepatoduodenal ligament, the dilated extrahepatic bile duct and a 1-cm length of hypoplastic cystic duct were found. Gallbladder agenesis is usually accompanied by the lack of the cystic duct. The present case is the third report of gallbladder agenesis with a patent or hypoplastic cystic duct.

    The risk of port-site metastasis after laparoscopic removal of incidental gallbladder cancer was previously estimated to be 14-30%. The present study was designed to determine the incidence of port-site metastasis in incidental gallbladder cancer in the modern era (2000-2014) versus the historic era (1991-1999). We also investigated the site of port-site metastasis. Using PRISMA, a systematic review was conducted to identify papers that addressed the development of port-site metastasis after laparoscopic resection of incidental gallbladder cancer. Studies that described cancer-specific outcomes in ≥5 patients were included. A validated quality appraisal tool was used, and a weighted estimate of the incidence of port-site metastasis was calculated. Based on data extracted from 27 papers that met inclusion criteria, the incidence of port-site metastasis in incidental gallbladder cancer has decreased from 18.6% prior to 2000 (95% confidence interval 15.3-21.9%, n = 7) to 10.3% since then (95% confidence interval 7.9-12.7%, n = 20) (P extraction site is at significantly higher risk than nonextraction sites. The incidence of port-site metastasis in incidental gallbladder cancer has decreased but remains high relative to other primary tumors. Any preoperative finding that raises the suspicion of gallbladder cancer should prompt further investigation and referral to a hepato-pancreato-biliary specialist. Copyright © 2016 Elsevier Inc.

    This paper presents a new approach to gallbladder ultrasonic image processing and analysis towards automatic detection and interpretation of disease symptoms on processed US images. First, in this paper, there is presented a new heuristic method of filtering gallbladder contours from images. A major stage in this filtration is to segment and section off areas occupied by the said organ. This paper provides for an inventive algorithm for the holistic extraction of gallbladder image contours, based on rank filtration, as well as on the analysis of line profile sections on tested organs. The second part concerns detecting the most important lesion symptoms of the gallbladder. Automating a process of diagnosis always comes down to developing algorithms used to analyze the object of such diagnosis and verify the occurrence of symptoms related to given affection. The methodology of computer analysis of US gallbladder images presented here is clearly utilitarian in nature and after standardising can be used as a technique for supporting the diagnostics of selected gallbladder disorders using the images of this organ.

    Anomalies of the gallbladder position in the biliary tract are rare, but they could be very dangerous during cholecystectomy. A 48-year-old man presented with a 2-week history of intermittent epigastric pain, scleral jaundice and elevation of liver function tests. After a magnetic resonance cholangiogram and an endoscopic retrograde cholangiogram with sphincterotomy, he was submitted to laparoscopic cholecystectomy, the conversion to laparotomy was decided for the suspect of gallbladder interposition. The anatomical anomaly was confirmed and a Roux-en-Y hepaticojejunostomy was executed, with end-to-side anastomosis between the confluence of the hepatic ducts and the fourth loop of jejunum, on a biliary stent. This catheter was removed in the tenth postoperative day; after cholangiography and CT abdominal scan the patient was discharged, without complications. The gallbladder interposition is a rare malformation which seems to arise from an embryonic anomaly occurring between the 4th and the 5th week and whose potential causes have not been detected. A similar outcome could be also determined by a Mirizzi syndrome, but in our case it is excluded because intra-operatively there was no inflammatory reaction that could justify the presence of a fistula between the gallbladder and the common hepatic duct. Once the gallbladder interposition is found, the surgical treatment consists in removing the gallbladder itself and the corresponding part of the common hepatic duct. The reconstruction is carried out by a Roux-en-Y hepaticojejunostomy with anastomosis at the hepatic hilum, positioning a biliary stent.

    Full Text Available The aim of this study was to detect the localisation of tyrosine hydroxylase (TH positive nerve fibres (THN and distribution of tyrosine hydroxylase positive mast cells (THMC in the wall of porcine gallbladder. THN were observed as single fibres, nerve fibres forming perivascular plexuses and nerve fibres grouped within the nerve fascicles. In the gallbladder`s fundus, body and neck, the TH+ fibres formed mucosal, muscular and serosal nonganglionated nerve plexuses. Toluidine blue (TB staining was used to confirm that the TH positive cells were mast cells. The number of THMC in the propria of gallbladder`s fundus, body and neck was significantly higher than in the muscular and serosal layers in both genders. The number of mast cells in the musculature was higher than in the serosa. The density and location of the THMC were similar to the TB positive (with gamma meta-chromasia mast cells in both males and females, and statistically significant difference was not established. In conclusion, original data concerning the existence and localisation of catecholaminergic nerves and THMC distribution in the porcine gallbladder’s wall are presented. The results could con-tribute to the body of knowledge of functional communication between autonomic nerves and mast cells in the gallbladder.

    An audit of 1122 cholecystectomies for a 6-year period from 2000 to 2005 was done to review cases of primary carcinoma of gallbladder. There were nine cases of primary carcinoma of gallbladder. Six were females and 3 males. Their ages ranged from 27 to 81 years. Pre-operatively, only 2 (11.1%) were clinically suspected of carcinoma while 3 were diagnosed as cholecystitis, two as cholelithiasis and one case each of ovarian cyst and intestinal obstruction. Intra-operatively, an additional four cases were suspected as gallbladder carcinoma with the remaining three cases diagnosed as only having gallstones. Altogether only 5 (55.6%) cases were associated with gallstones. Six (66.67%) cases of gallbladder carcinoma had abnormal macroscopical lesions noted; either papillary lesions or polypoid masses. The remaining 3 cases had thickening of the wall, consistent with chronic cholecystitis. Seven cases were found histologically to be adenocarcinoma. Of these, two were papillary carcinoma and one signet ring cell type adenocarcinoma. One case of squamous cell carcinoma and one case of adenosquamous carcinoma were noted. This study highlights the importance of careful macroscopical and microscopical evaluation of a routine pathological examination of gallbladder removed for cholecystitis or cholelithiasis. It provides the incidence of gallbladder carcinoma in patients who underwent cholecystectomies in a government hospital in Johor, Malaysia.

    Full Text Available Abstract Introduction Primary gallbladder neuroendocrine tumors are extremely rare, representing 0.2% of all neuroendocrine tumors. The diagnosis is incidental in most cases. Case presentation We describe the case of a 57-year-old Caucasian man who underwent laparoscopic cholecystectomy for the evaluation of a gallbladder polyp that had been incidentally detected by ultasonography. Histologically, his lesion was composed of monomorphic cells that contained small round nuclei and that were organized in small nodular, trabecular, and acinar structures. His cells were positive for chromogranin A and synaptophysin, and a diagnosis of "typical" carcinoid of the gallbladder was made. His post-operative computerized axial tomography, 111In-pentetreotide scintigraphy, and hormone-specific marker results were negative. He is disease-free 45 months after surgical treatment. Conclusions Characteristic pathological findings of the gallbladder neuroendocrine tumors predict the prognosis. Whereas classical carcinoids of the gallbladder only rarely have a metastatic or invasive phenotype, the "atypical" variants are more aggressive and are associated with a poorer prognosis. Given the difficulty in distinguishing between benign and malignant lesions in the pre-surgical setting, we tend to consider each polypoid-like lesion of the gallbladder to be a high-risk lesion if it is larger than 1 cm and, as a result, to emphasize the need for cholecystectomy in all cases, relying on the pathological and immunohistochemistry analyses for the final diagnosis.

    Cavernous hemangiomas of the gastrointestinal tract are quite rare and, until now, have been difficult to diagnose preoperatively due their nonspecific presentations and imaging features, as well as a lack of histologic description pertaining to small superficial biopsies such as those obtained endoscopically. We report a unique case of a 4 cm transmural cavernous hemangioma in the terminal ileum with literature review and describe a new histologic finding—the “endothelialized muscularis mucosae,” which was discovered upon review of the endoscopic biopsy and could potentially facilitate preoperative diagnosis of these lesions from endoscopic biopsies in the future. These lesions have classically required surgical resection in order to make a definitive diagnosis and rule out malignancy, with which they share many historical and radiographic features. Due to their potential to cause bowel obstruction, intussusception, perforation, and hemorrhage, these lesions may ultimately require surgical resection to relieve symptoms or prevent or treat complications—however, surgical planning and patient counseling could be greatly improved by a preoperative diagnosis. Therefore, gastroenterologists, pathologists, and surgeons should be aware of the “endothelialized muscularis mucosae” which can be very helpful in diagnosing GI cavernous hemangiomas from endoscopic biopsies.

    Full text: Recent literature suggests that an infusion of 0.02 (g/Kg of CCK results in a narrower range of normal GBEF than an infusion 0.01(g/Kg of. Our aim was to investigate the effect of a 30-minutes infusion of 0.02 (g/Kg, in patients with a low probability of gallbladder disease. Sixty patients presenting with abdominal symptoms were referred to West mead Medical Imaging over a 9-month period for DISIDA biliary scans. 1-minute dynamic images were collected over 90 minutes. The CCK infusion was commenced when the gallbladder was well filled. GBEF was calculated from background corrected time activity curves over the gallbladder. Sixteen patients were excluded because of previous cholecystectomy or known gallbladder disease. Thirty-three patients were considered to have a low probability of gallbladder disease after final diagnoses were obtained from referring doctors. The mean GBEF for this group was 65.6%, SD 17.2 with a mean range 28-98% compared with mean 56.9%, SD 18.1 with a mean range 21-85% of our previous study using 0.01(gCCK. Females exhibited lower GBEFs than males while females under 50 gave the lowest mean. We concluded that the higher dose infusion causes more complete gallbladder emptying, and that there is a difference in GBEF between males and females of different ages. We question the validity of the same 'Normal' range being applied to both genders and all age groups. Copyright (2003) The Australian and New Zealand Society of Nuclear Medicine Inc

    The incidence of gallbladder sludge or gallstone formation in bedridden patients with cerebrovascular disease (CVD) remains obscure. The aim of this study was to determine the incidence, relationship to feeding method, and mechanisms of gallbladder sludge and gallstone formation in elderly patients with CVD. Using ultrasonography, we determined the development of gallbladder sludge and gallstone over a 12-month period, the area of the gallbladder, the gallbladder contractile response to cerulein, and fasting levels of plasma cholecystokinin (CCK) in 40 bedridden elderly patients with CVD. The patients were divided into three groups based on the feeding method: oral ingestion (OI), nasogastric feeding (NF), and total parenteral nutrition (TPN). Gallbladder sludge and gallstone were not observed in any of the 14 OI patients, but occurred in 6 and 1 of the 11 NF patients, and in 14 and 3 of the 15 TPN patients, respectively. Fasting gallbladder areas were significantly larger in the TPN group than in the other two groups. The TPN group showed a marked decrease in cerulein-induced gallbladder contractility. Fasting plasma CCK levels were lower in the TPN group than in the OI group. Our results indicate that elderly patients with CVD confined to bed over long periods are not necessarily at risk of gallbladder sludge or gallstone formation, and the development of these features may be associated with the feeding method. The predisposition of CVD patients on TPN to gallbladder disease is probably caused by failure of gallbladder contraction, resulting from insufficient secretion of CCK and impaired sensitivity of the gallbladder to CCK.

    Gallbladder injuries are extremely rare in blunt trauma, with a reported incidence of <2%. We report an autopsy case of fatal hemorrhagic shock due to intra-abdominal bleeding resulting from complete avulsion of the gallbladder associated with liver cirrhosis. Multiplanar images derived from multislice computed tomography (MSCT) performed as part of pre-autopsy screening showed complete avulsion of the gallbladder without any other associated intra-abdominal injuries, facilitating forensic autopsy planning. In this report, we discuss the role of MSCT in cases of fatal intra-abdominal bleeding caused by avulsion of the gallbladder and discuss the mechanism of this injury

    2013-01-01

    Background Neurotrophic factors such as brain derived neurotrophic factor (BDNF) are synthesized in a variety of neural and non-neuronal cell types and regulate survival, proliferation and apoptosis. In addition, bone morphogenetic proteins (BMPs) inhibit the proliferation of pulmonary large carcinoma cells bone morphogenetic protein receptor, type IA (BMPR1A). Little is known about the expression of BDNF or BMPR1A in malignant gall bladder lesions. This study was to evaluate BDNF and BMPR1A expression and evaluate the clinicopathological significance in benign and malignant lesions of the gallbladder. Methods The BDNF and BMPR1A expression of gallbladder adenocarcinoma, peritumoral tissues, adenoma, polyp and chronic cholecystitis were Immunohistochemically determined. Results BDNF expression was significantly higher in gallbladder adenocarcinoma than in peritumoral tissues, adenoma, polyps and chronic cholecystitis samples. However, BMPR1A expression was significantly lower in gallbladder adenocarcinoma than in peritumoral tissues, adenomas, polyps and chronic cholecystitis tissues. The specimens with increased expression of BDNF in the benign lesions exhibited moderate- or severe-dysplasia of gallbladder epithelium. BDNF expression was significantly lower in well-differentiated adenocarcinomas with maximum tumor diameter 2 cm, metastasis of lymph node, and invasiveness of regional tissues in gallbladder adenocarcinoma. BMPR1A expression were significantly higher in the well-differentiated adenocarcinoma with maximal tumor diameter 2 cm, metastasis of lymph node, and invasiveness of regional tissues in gallbladder. Univariate Kaplan-Meier analysis indicated increased expression of BDNF or decreased expression of BMPR1A was associated with decreased disease specific survival (DSS) rates. Similarly, multivariate Cox regression analysis showed increased expression of BDNF or decreased expression of BMPR1A are independent predictors of poor DSS rates in gallbladder

    Full Text Available BackgroundGallbladder cancer is sometimes incidentally uncovered following cholecystectomy for gallstones diseases. The supposed highly variable prevalence of incidental gallbladder cancer through our country is unknown.ObjectiveTo explore the prevalence of incidental gallbladder cancer in our tertiary-care hospital.MethodsA cross-sectional study was carried out on patients who consecutively underwent cholecystectomy due to gallstones disease at Faculdade Pernambucana de Saúde, Instituto de Medicina Integral Professor Fernando Figueira - FPS/IMIP, from January, 2007 to December, 2010. Data on incidental gallbladder cancer patients were explored for prevalence estimation and description of our experience with the management of this malignancy.ResultsOur analysis involved 2018 patients with a marked predominance of women (n=1.697; 84.1% over men (n=321; 15.9%. The 3-year prevalence estimate of 0.34% was recorded for incidental gallbladder cancer in our sample. Regarding tumor staging, there were 1 T1a, 1 T1b, and 5 T2 adenocarcinoma tumors. Laparoscopic cholecystectomy alone was performed for the T1a tumor, and additional radical surgery was performed in five others. One patient presented metastatic disease at the time of repeat surgery. The final pathology revealed residual/additional disease in all T2 tumors after radical surgery whereas the T1b patient underwent a salvage Whipple’s procedure due to a secondary distal cholangiocarcinoma. The patient with T1a tumor is alive after 3-year follow-up but all of the others died because of disease recurrence/progression up to 12 months.ConclusionThis study confirms the poor prognosis of Gallbladder cancer even when incidentally diagnosed following cholecystectomy and supposes a 3-year prevalence estimate of 0.34% for incidental gallbladder cancer in our Center from Pernambuco State, Brazil.

    To evaluate the methods and outcome of gallbladder preservation in surgical treatment of primary bile duct stones. Thirty-five patients with primary bile duct stones and intact gallbladders received stone extraction by two operative approaches, 23 done through the intrahepatic duct stump (RBD-IDS, the RBD-IDS group) after partial hepatectomy and 12 through the hepatic parenchyma by retrograde puncture (RBD-RP, the RBD-RP group). The gallbladders were preserved and the common bile duct (CBD) incisions were primarily closed. The patients were examined postoperatively by direct cholangiography and followed up by ultrasonography once every six months. In the RBD-IDS group, residual bile duct stones were found in three patients, which were cleared by a combination of fibrocholedochoscopic extraction and lithotripsy through the drainage tracts. The tubes were removed on postoperative day 22 (range: 16-42 days). In the RBD-RP group, one patient developed hemobilia and was cured by conservative therapy. The tubes were removed on postoperative day 8 (range: 7-11 days). Postoperative cholangiography showed that all the gallbladders were well opacified, contractile and smooth. During 54 (range: 6-120 months) months of follow-up, six patients had mildly thickened cholecystic walls without related symptoms and further changes, two underwent laparotomies because of adhesive intestinal obstruction and gastric cancer respectively, three died of cardiopulmonary diseases. No stones were found in all the preserved gallbladders. The intact gallbladders preserved after surgical extraction of primary bile duct stones will not develop gallstones. Retrograde biliary drainage is an optimal approach for gallbladder preservation.

    To determine whether radiofrequency thermal ablation can be used to treat benign cystic lesions in a porcine gallbladder model. This experimental study of radiofrequency thermal ablation involved the use of 15 exvivo porcine gallbladders and 15-G expandable needle electrodes. To investigate optimal temperature parameters, three groups of five were designated according to target temperature:Group A: 70 deg C; Group B: 80 deg C; Group C: 90 deg C. After the target temperature was reached, ablation lasted for one minute. Gallbladder width, height and length were measured before and after ablation , and the estimated volume reduction ratios of the three groups were compared. Whether adjacent liver parenchyma around the gallbladder fossa was ablated by heat conducted from hot bile was also determined, and the thickness of the ablated area of the liver was measured. The volume reduction ratio in Group A, B and C was 42.7%, 41.7% and 42.9%, respectively (ρ>.05). In all 15 cases, gallbladder walls lost their transparency and elasticity at about 70 deg C. In nine of ten cases in Groups B and C, the hepatic capsule around the gallbladder fossa was retracted at about 80 deg C. The mean thickness of liver parenchymal damage adjacent to the gallbladder was 5.4 mm in Group B and 9.8 mm in Group C. In Group A livers, only one case showed minimal gradual parenchymal change. Microscopically, all three groups showed complete coagulation necrosis of the wall. On the basis of this feasibility study, radiofrequency thermal ablation is potentially suitable for the ultrasound-guided treatment of symptomatic cystic lesions including benign hepatic or renal cyst

    A retrospective review of 72 patients with locally advanced gallbladder carcinoma, between January 1900 and December 1996, was performed. Survival results and prognostic factors are analyzed for the patients treated with a various modalities. The patients were classified by treatment modality: group 1 included to 27 patients treated with palliative surgery alone, and group 2 for 11 patient treated with palliative surgery and radiotherapy; group 3 for 18 patients not treated by any treatment modality, and group 4 for 16 patients treated with radiotherapy alone. Age distribution ranged from 35 to 80 years with a mean of 63 years. The stage was classified by TNM and Nevin's staging system; all patients had an advanced stage more than III. Palliative surgery was done in 3B patients and adjuvant radiation therapy (Rl1 was followed in 11. For 34 patients, in whom no resection was tried, definitive RT was done in 16. Radiation delivered to tumor site and draining nodes up to 45-612 Gy using 10 MY linear accelerator. Chemotherapy was given to 25 patients with 5-FU based regimens. Median survival time was 10.3 months and 3-year survival rates (3-YSR) were 13.0% in all patients. Survival rates according to the treatment modalities were as followed; in palliative surgery alone, 3-YSR was 2.5%; in palliative surgery and adjuvant RT, 3-YSR was 45.5%; in no treatment group, 3YSR were 8.3%; and definitive RT was 13.1%. It was better survival in additional RT after palliative surgery group than palliative surgery alone (p=0.0009). It was better survival in definitive RT group than no treatment group (p=0.022). Significant prognostic factors by multivariate analysis were treatment modalities, the type of tumor and TNM stage. Significant prognostic factors by multivariate analysis were treatment modalities, the type of tumor and the presence of jaundice. It is suggested that RT could be potentially effective as adjuvant treatment modalities after palliative surgery or primary

  3. The microbiological and clinical characteristics of invasive salmonella in gallbladders from cholecystectomy patients in kathmandu, Nepal.

    Full Text Available Gallbladder carriage of invasive Salmonella is considered fundamental in sustaining typhoid fever transmission. Bile and tissue was obtained from 1,377 individuals undergoing cholecystectomy in Kathmandu to investigate the prevalence, characteristics and relevance of invasive Salmonella in the gallbladder in an endemic area. Twenty percent of bile samples contained a Gram-negative organism, with Salmonella Typhi and Salmonella Paratyphi A isolated from 24 and 22 individuals, respectively. Gallbladders that contained Salmonella were more likely to show evidence of acute inflammation with extensive neutrophil infiltrate than those without Salmonella, corresponding with higher neutrophil and lower lymphocyte counts in the blood of Salmonella positive individuals. Antimicrobial resistance in the invasive Salmonella isolates was limited, indicating that gallbladder colonization is unlikely to be driven by antimicrobial resistance. The overall role of invasive Salmonella carriage in the gallbladder is not understood; here we show that 3.5% of individuals undergoing cholecystectomy in this setting have a high concentration of antimicrobial sensitive, invasive Salmonella in their bile. We predict that such individuals will become increasingly important if current transmission mechanisms are disturbed; prospectively identifying these individuals is, therefore, paramount for rapid local and regional elimination.

    In patients with stones in their bile ducts and gallbladders, cholecystectomy is generally recommended after endoscopic sphincterotomy and clearance of bile duct stones. However, only approximately 10% of patients with gallbladders left in situ will return with further biliary complications. Expectant management is alternately advocated. In this study, we compared the treatment strategies of laparoscopic cholecystectomy and gallbladders left in situ. We randomized patients (>60 years of age) after endoscopic sphincterotomy and clearance of their bile duct stones to receive early laparoscopic cholecystectomy or expectant management. The primary outcome was further biliary complications. Other outcome measures included adverse events after cholecystectomy and late deaths from all causes. One hundred seventy-eight patients entered into the trial (89 in each group); 82 of 89 patients who were randomized to receive laparoscopic cholecystectomy underwent the procedure. Conversion to open surgery was needed in 16 of 82 patients (20%). Postoperative complications occurred in 8 patients (9%). Analysis was by intention to treat. With a median follow-up of approximately 5 years, 6 patients (7%) in the cholecystectomy group returned with further biliary events (cholangitis, n = 5; biliary pain, n = 1). Among those with gallbladders in situ, 21 (24%) returned with further biliary events (cholangitis, n = 13; acute cholecystitis, n = 5; biliary pain, n = 2; and jaundice, n = 1; log rank, P = .001). Late deaths were similar between groups (cholecystectomy, n = 19; gallbladder in situ, n = 11; P = .12). In the Chinese, cholecystectomy after endoscopic treatment of bile duct stones reduces recurrent biliary events and should be recommended.

    Full Text Available Introduction: The former studies have shown the presence of As and Sb in deposits of the gallbladder. The aim of studies: The aim of the studies was to define the level of accumulation of Pb, Cd, Zn in deposits of the gallbladder as supplementary biological test for exposure assessment in a long run. Materials and methods: Pb, Cd and Zn content was investigated with inductive coupled plasmaatomic emission spectrometry were deposits of the gallbladder in men and women living in the Silesia Region. Results: The change of these elements content was analyzed in connection with behavioral factors ( diet, alcohol, coffee, obesity and tobacco addiction of the gender. Attention was drawn to the probability of interaction of Pb, Cd, Zn with other elements during their accumulation in deposits of the gallbladder. It appeared that deposits of the gall bladder can be used as an additional biological test in individual exposure assessment to Pb, Cd and Zn. It was noted that the level of content of Pb, Zn and Cd in deposits of the gallbladder is impacted by behavioral factors (diet, alcohol, coffee, obesity tobacco addiction. A characteristic impact of the tobacco addiction on the rise in the content of lead, cadmium and zinc was demonstrated as well as significant role of the presence of these elements in the total environmental pollution in relevant living areas.

    A source of frustration during laparoscopic cholecystectomy involves extraction of the gallbladder through port sites smaller than the gallbladder itself. We describe the development and testing of a novel device for the safe, minimal enlargement of laparoscopic port sites to extract large, stone-filled gallbladders from the abdomen. The study device consists of a handle with a retraction tongue to shield the specimen and a guide for a scalpel to incise the fascia within the incision. Patients enrolled underwent laparoscopic cholecystectomy. Gallbladder extraction was attempted. If standard measures failed, the device was implemented. Extraction time and device utility scores were recorded for each patient. Patients returned 3-4 weeks postoperatively for assessment of pain level, cosmetic effect, and presence of infectious complications. Twenty (51 %) of 39 patients required the device. Average extraction time for the first eight patients was 120 s. After interim analysis, an improved device was used in 12 patients and average extraction time was 24 s. There were no adverse events. Postoperative pain ratings and incision cosmesis were comparable between patients with and without use of the device. The study device enables safe and rapid extraction of impacted gallbladders through the abdominal wall.

    A dural metastasis is one of the essential differential diagnoses of meningioma. In general, carcinomas of the breast and lung in females and prostate in males have been the most commonly reported primary lesions of dural metastases. However, dural metastasis of gallbladder carcinoma is extremely rare. Here, we report a unique case of a dural matter metastasis of gallbladder carcinoma as the first manifestation, which was autopsy-defined as small cell carcinoma. A 78-year-old man came to our hospital complaining of left hemianopia. Brain computed tomography (CT) revealed a sizeable parasagittal dural-based extra-axial tumor. However, the findings for meningioma were atypical by magnetic resonance imaging, suggesting a meningioma mimic. A contrast-enhanced CT scan of the abdomen revealed a large gallbladder carcinoma. The patient opted for the best supportive care and died 2 months later. The post-mortem examination revealed small cell carcinoma in gallbladder carcinoma. Moreover, an immunologically similar carcinoma was detected in the dural metastasis. To the best of our knowledge, this is the first case of a dural metastasis of gallbladder small cell carcinoma. A systemic examination is essential for clinicians when atypical findings of meningioma are observed, suggesting a meningioma mimic. We present this rare case with a review of the literature.

    Gallbladder cancer (GBC) is a highly fatal disease with poor prognosis and 5-year survival nutritional deterioration are associated with adverse outcomes in terms of cancer prognosis. Protein-calorie malnutrition is the single most common secondary diagnosis in a patient with cancer, and is a direct consequence of the anorexia of malignancy and altered host metabolism induced by the tumor. The present study of nutritional assessment is of particular interest for it helps in better understanding the extent of malnutrition in patients of GBC. A case-control study was designed comprising of 153 cases of GBC and 153 controls of gallstone disease (GSD). To assess the nutritional status of the GBC patients, anthropometric measurements such as height, weight, mid arm circumference, and skinfold thickness were recorded together with the biochemical parameters and their nutrient intake. The present study showed that GBC influences the nutritional status of the patients. Forty-three percent of GBC patients were malnourished with low body mass index (BMI). A significant reduction in all the anthropometric measures was observed for GBC patients compared to those with GSD. GBC patients had significantly low hemoglobin and serum albumin levels compared to the control group. The hemoglobin levels in case and control groups were 10.87 g/dl (+/-1.81 SD) and 11.62 g/dl (+/-1.89 SD), respectively (P anorexia and weight loss. Copyright 2006 Wiley-Liss, Inc.

    In this article, we report the current surgical approach to gallbladder disease at a major referral hospital in rural Guatemala. Complications in a cohort of patients undergoing open versus laparoscopic cholecystectomy were catalogued. We reviewed cholecystectomies performed by surgeons at the Hospital Nacional de San Benito in El Peten, Guatemala, after the adoption of the laparoscopic approach. Laparoscopic cholecystectomies (LCs) between 2014 and 2015 (n = 42) were reviewed and matched by 58 randomly selected open cholecystectomies (OCs) during the same period. Patient demographics were similar in the LC and OC groups. Of the 63 patients who had elective surgery, 43 (68%) underwent OC. Conversion rate, hospital length of stay, and readmission rate were 4%, 4.8 days, and 5%, respectively. Complications were similar between groups. Despite the low number of LCs, their complications were not different from that of OCs. During the study period, a large number of cholecystectomies continued to be open, even in the elective setting. Published by Elsevier Inc.

    To investigate the expression of p21 and p27 factors in gallbladder cancer (GBC), and to correlate their expression with clinicopathological parameters: age, gender, stage, invasion and grade. Thirty-two surgically resected specimens were collected between 1994-2001 from different health centers in north Jordan. Tissues belong to 25 females and 7 males were examined immunohistochemically. The study took place in the Pathology Department, Jordan University of Science and Technology, Jordan. Levels of p21 were found in 75% and p27 in 25%. Furthermore, p21 was expressed in 50% of the specimens which belong to patients with ages 64 years have p 21WAF1/CIP1 expression (p=0.001). The expression of p21 between advanced stages (stages III and IV) was 89.5% and early stages (stages I and II) was 53.8% (p=0.031). The p27 expression was markedly decreased in GBC cases (25%) and there were no significant correlation between p27KIP1 expression and all clinicopathological parameters including gender, World health Organization grades, stages and invasion, whereas expression of p21 was 75% and there was a significant correlation between p21 and clinicopathological parameters including gender, stages and invasion.

    Percutaneous transhepatic gallbladder drainage (PTGBD) is a procedure to resolve acute cholecystitis (AC). It may decrease the technical difficulty of laparoscopic cholecystectomy (LC) and thus may facilitate successful surgery when a patients' condition improves. However, the timing of LC after PTGBD remains controversial. From 2004 to 2010, cholecystectomy after PTGBD was performed in 67 patients with AC. Group I members underwent LC within 72 h of PTGBD (n = 21), whereas group II members underwent LC at more than 72 h after PTGBD (n = 46). The open conversion rate was similar in the two groups. The perioperative complication rate was higher in group I than in group II, but with marginal significance (19.0 vs. 4.3%; p = 0.07). Mean operative time was longer in group I than in group II (79.3 ± 25.3 vs. 53.7 ± 45.3 min; p = 0.02). However, overall hospital stay was shorter in group I than in group II, but with marginal significance (10.8 ± 4.5 vs. 14.7 ± 9.3 days; p = 0.08). Pros and cons were well balanced between the two groups. Decisions on the timing of cholecystectomy after PTGBD should be made based on considerations of patient condition, hospital facilities, and surgical experience.

    Many risk factors have been identified in minimally invasive cholecystectomies that lead to higher complications and conversion rates. No study that we encountered looked at nonvisualization of the gallbladder (GB) during surgery as a risk factor. We hypothesized that nonvisualization was associated with an increased risk of complications and could be an early intraoperative identifier of a higher risk procedure. Recognizing this could allow surgeons to be aware of potential risks and to be more likely to convert to open for the safety of the patient. We looked at minimally invasive cholecystectomies performed at our institution from January 2015 through April 2016 and had the performing resident fill out a survey after the surgery. Outcomes were conversion rates, intraoperative complications, and blood loss and were analyzed via Pearson χ 2 test or Mann-Whitney U test. The primary outcome showed a conversion rate of 37% in nonvisualized GBs versus 0% in visualized ( P = .001). Secondary outcomes showed significant differences in GB perforations (74% vs 13%, P = .001), omental vessel bleeding (16% vs. 0%, P = .005), and EBL (46 mL vs 29 mL, P = .001). Intraoperative nonvisualization of the GB after adequate positioning caused significantly increased risk of intraoperative complications and conversion. This knowledge could be useful during intraoperative assessment, to decide whether a case should be continued as a minimally invasive procedure or converted early to help reduce risk to the patient. Further randomized controlled studies should be performed to further demonstrate the value of this assessment.

    To retrospectively investigate clinical outcome and differential CT features of gallbladder (GB) neuroendocrine tumours (NETs) from adenocarcinomas (ADCs). Nineteen patients with poorly-differentiated (PD) NETs and 19 patients with PD ADCs were enrolled. Clinical outcome was compared by the Kaplan-Meier method. We assessed qualitative and quantitative CT features to identify significant differential CT features of PD NETs from ADCs using univariate and multivariate analyses. Receiver operating characteristic (ROC) analysis was used for quantitative CT features. PD NETs showed poorer prognosis with significantly shorter median survival days than ADCs (363 vs. 590 days, P = 0.03). On univariate analysis, NETs more frequently manifested as GB-replacing type and showed well-defined margins accompanied with intact overlying mucosa. On multivariate analysis, well-defined margin was the sole significant CT differentiator (odds ratio = 27.817, P = 0.045). Maximum size of hepatic and lymph node (LN) metastases was significantly larger in NETs (11.0 cm and 4.62 cm) than ADCs (2.40 cm and 2.41 cm). Areas under ROC curves for tumour-to-mucosa ratio, maximum size of hepatic and LN metastasis were 0.772, 0.932 and 0.919, respectively (P < 0.05). GB PD NETs show poorer prognosis than ADCs. Well-defined margin, larger hepatic and LN metastases are useful CT differentiators of GB NETs from ADCs. (orig.)

    The gallbladder is an unusual location of pancreatic heterotopia, defined as the presence of pancreatic tissue lacking anatomical and vascular continuity with the main body of the gland. A 28-year-old man presented with anorexia, nausea and pain in the right upper abdomen. On physical examination, the abdomen was tender to palpation and Murphy sign was positive. The patient underwent a cholecystecomy. This case, in our opinion, is very interesting since it permits to consider a controversial issue in the pathology of the gallbladder. The histological appearance of ductal structure in pancreatic heterotopia resembles the histological picture of both Aschoff-Rokitansky (AR) sinuses and adenomyomas. This finding suggests that these lesions are linked by a common histogenetic origin. We suggest that the finding of an adenomyoma in the gallbladder should prompt an extensive sampling of the organ in order to verify the coexistence of pancreatic rests. PMID:16586554

    The aim of this study was to analyze the gallbladder motor function in chronic pancreatitis (C) patients. Gallbladder emptying was evaluated in 11 patients, without and with addition of pancreatic extract and in ten controls. The results were compared and analyzed statistically. The ejection fraction (E F) of the gallbladder (GB) at 30, 45 and 60 minutes were calculated by using Tc-9 9 m DISIDA scintigraphy. The E F of GB at 60 minutes was significantly higher in the controls when compared to patients, although the results between patients were similar without and with addition of pancreatic extract. The results suggest that the delay in the GB emptying does not depend on the eventual alteration in the intestinal phase of the vesicular stimulation, but it probably results from a mechanic factor, which depends on the chronic pathological process located in the head of the pancreas.

    According to published reports, a common feature of xanthogranulomatous cholecystitis is the presence of intramural hypoattenuated nodules in thickened gallbladder wall. These nodules can, however, also be seen in pathological conditions such as acute cholecystitis, hyperplastic cholecystoses (cholesterolosis and adenomyomatosis), gallbladder cancer, and other inflammatory diseases such as tuberculosis. Retrospective review of the abdominal CT findings in 622 patients who for various reasons underwent cholecystectomy during a one-year period showed that intramural nodules were present in 60. In this pictorial essay we illustrate the imaging features of the many different pathological conditions which give rise to intramural hypoattenuated nodules in thickened wall of the gallbladder, correlating these features with the histopathological findings

    The use of laparoscopic surgery in the treatment of Mirizzi syndrome is considered controversial due to the degree of technical difficulty. We herein describe the case of a 36-year-old woman who was admitted to our hospital due to appetite loss, nausea and back pain. Endoscopic retrograde cholangiography revealed a round-shaped filling defect at the confluence of the bile duct. The patient was diagnosed with Mirizzi syndrome Type II according to the Csendes classification. Before surgery, an endoscopic nasobiliary drainage tube was placed for intraoperative cholangiography. Based on the intraoperative findings, the anterior wall of Hartmann's pouch was excised to remove the impacted gallstone. The neck portion of the gallbladder wall was then used to make a gallbladder patch, which was sutured to cover the anterior wall of the common hepatic bile duct. Laparoscopic choledochoplasty using a gallbladder patch was a technically feasible treatment for Mirizzi syndrome Type II.

    An 86 year-old woman with a past medical history significant for abdominal hernia and Alzheimer dementia presented to the Emergency Department with a 24 hour history of acute right upper quadrant pain associated with nausea and non-bilious emesis. Physical exam revealed right sided abdominal tenderness with associated mass. All laboratory values were within normal ranges. Both abdominal ultrasound and computed tomography of the abdomen/pelvis revealed a large distended gallbladder with wall thickening and gallstones. Based on presentation and radiologic findings, the emergency general surgery service was consulted for suspected acute cholecystitis. The patient was then admitted for intravenous antibiotics and scheduled for laparoscopic cholecystectomy the following day. Intra-operative findings revealed volvulus with acute necrosis of the entire gallbladder. The gallbladder had a long pedunculated cystic duct and artery that was detorsed before proceeding with resection. Postoperatively, the patient did well and was discharged a few days later tolerating a regular diet

He denied any history of alcohol consumption or cholecystitis and smoking. Hepatitis B surface antigen test and antihepatitis C antibody test were found to be negative. Serum carbohydrate antigen 19-9 (CA19-9 and carcinoembryonic antigen were elevated (CA19-9 was 59.92 U/mL and carcinoembryonic antigen was 12.64 ng/mL, whereas alpha-fetoprotein was below the normal limit (2.46 ng/mL. Computed tomography scan revealed a solid mass with measurements of 4.6×5.6×7.1 cm, which nearly filled the whole gallbladder space. Radical cholecystectomy, including segments IV B and V of the liver and lymphadenectomy, was performed. The neoplasm in gallbladder was completely resected, and the patient obtained a negative margin. Histological and immunohistochemical profile suggested a clear cell adenocarcinoma of the gallbladder with hepatoid differentiation. After reviewing the literature, we reported that this case is the first identified case of cell adenocarcinoma of the gallbladder with extensive hepatoid differentiation. However, clinical features of clear cell adenocarcinoma with hepatoid differentiation remain unclear due to the extremely rare incidence. There was no indication of adjuvant chemotherapy and no literature has been reported on the application of chemotherapy. This case showed a promising clinical outcome after curative resection, which indicated that surgical treatment could be potentially considered for suitable patients.

    Gallbladder carcinoma (GBC) is one of the most lethal malignancies of upper gastrointestinal tract and it has the highest mortality rate in Chile and India. It has a very high incidence rates in northern India therefore it is also called as an Indian disease. There are several factors which play important role in development of gallbladder cancer including long-standing stones in gallbladder and alterations in composition of bile. Studies on gallstones and gallbladder tissues revealed that benign group can easily be discriminated from malignant group. Many proteomic studies have been performed for different cancers and several responsible serum protein markers have been identified but there is no such metabonomics study that shows the presence of any biomarker associated with gallbladder carcinoma. Identification of such biomarker would help immensely in the diagnostic of GBC. For this study we have collected blood samples (70; including patients from Chronic Cholecystitis (CC), XanthoGranulomatous Cholecystitis (XGC) and Gallbladder Cancer (GBC)) post-operatively (immediately after surgery) from patient undergoing cholecystectomy in Department of Surgical Gastroenterology, SGPGIMS. Control samples were also collected from 20 volunteers after 12 hrs of fasting. 4 ml of blood sample was collected and was allowed to clot in plastic tube for 30 min at room temperature in incubator. The serum was collected by centrifugation and samples were stored at -80 deg C till NMR experiments. 400 μL of serum was used for recording NMR spectra. NMR spectra were recorded at Bruker Avance 800 MHz spectrometer using CPMG pulse sequence with water presaturation. Control serum shows presence of various amino acids and low molecular weight metabolites. Detailed multivariate analysis along with markers found in serum associated with GBC will be presented.

    Endoscopic sphincterotomy (EST) with stone extraction is the standard management for choledocholithiasis. However, the necessity for subsequent management of gallstone to prevent the biliary complications remained controversial and few data were evaluated for the impact of status of gallbladder on recurrent biliary complications. We retrospectively investigated the relationship between the status of gallbladder and the occurrence of biliary complications after endoscopic removal of choledocholithiasis. Between January 1998 and December 2008, we enrolled 453 patients with intact gallbladder who underwent EST for choledocholithiasis and allocated into two groups: calculous gallbladder (n = 256) and acalculous gallbladder (n = 197). By reviewing patients' medical records, we compared the occurrence of biliary complications according to the presence or absence of gallstone in GB in situ. In total, biliary complications occurred in 83 patients (18.3 %) during the follow-up period. Calculous GB group had higher rate of overall complications (22.7 vs. 12.7 %; p = 0.007) and GB-associated complications (11.3 vs. 2.5 %; p = 0.001) than acalculous GB group. On the multivariate analysis, only the presence of gallstone was shown to be significant risk factor for overall biliary complication (OR 2.029; 95 % CI 1.209-3.405; p = 0.007) and GB-associated complications (OR 5.077; 95 % CI 1.917-13.446; p = 0.001). Mean event-free period was shorter in calculous GB group than acalculous GB group for overall complications (1774 vs. 2159 days; p = 0.012) and GB-associated complication (2153 vs. 2591 days; p = 0.001). Prophylactic cholecystectomy may not be necessary to prevent biliary complication in patients with acalculous gallbladder after endoscopic removal of pigment stones from bile duct.

    To compare receptors for cholecystokinin (CCK) in pancreas and gallbladder, we measured binding of 125I-Bolton-Hunter-labeled CCK-8 (125I-BH-CCK-8) to tissue sections from guinea pig gallbladder and pancreas under identical conditions. In both tissues, binding had similar time-, temperature-, and pH dependence, was reversible, saturable and inhibited only by CCK related peptides or CCK receptor antagonists. Autoradiography localized 125I-BH-CCK-8 binding to the smooth muscle layer in the gallbladder. Binding of 125I-BH-CCK-8 to gallbladder sections was inhibited by various agonists with the following potencies (IC50):CCK-8 (0.4 nM) greater than des(SO3)CCK-8 (0.07 microM) greater than gastrin-17-I (1.7 +/- 0.3 microM) and by various receptor antagonists with the following potencies: L364,718 (1.5 nM) greater than CR 1409 (0.19 microM) greater than asperlicin = CBZ-CCK-(27-32)-NH2 (1 microM) greater than Bt2cGMP (120 microM). Similar potencies were found for the agonists and antagonists for pancreas sections. Inhibition of binding of 125I-BH-CCK-8 by 11 different analogues of proglumide gave similar potencies for both pancreas and gallbladder. The potencies of agonists in stimulating and antagonists in inhibiting CCK-stimulated contraction or amylase release correlated closely with their abilities to inhibit 125I-BH-CCK-8 binding to gallbladder or pancreas sections or acini, respectively. The present results demonstrate and characterize a method that can be used to compare the CCK receptors in guinea pig gallbladder and pancreas under identical conditions. Moreover, this study demonstrates that gallbladder and pancreatic CCK receptors have similar affinities for the various agonists and antagonists tested and, therefore, provides no evidence that they represent different subtypes of CCK receptors that can be distinguished pharmacologically

    Fourteen patients with carcinomas of the gallbladder and eight patients with biliary duct carcinomas were examined by CT, sonography, percutaneous transhepatic cholangiography (PTC), endoscopic retrograde cholangiography (ERC) and angiography. The results were compared retrospectively. Sonography proved suitable as a screening method. For accurate demonstration, this should be supplemented by C.T.. PTC and ERC demonstrate intraductal extension of biliary carcinomas and of gallbladder carcinomas infiltrating the bile ducts. The value of angiography consists merely in the pre-operative demonstration of the vascular anatomy. (orig.) [de

    Full Text Available Background. Breast carcinoma is the most common malignancy in women worldwide. It is most commonly associated with metastases to the liver, lung, bone, and the brain. Invasive lobular carcinoma is a less common pathology with slightly higher metastases to the upper gastrointestinal tract. Invasive lobular carcinoma metastasis to the gallbladder is extremely rare. Method. In this paper we are presenting a case of a 67-year-old female with metastases of invasive lobular breast cancer to the gallbladder six years after her therapy. Conclusion. This case clearly signifies the nature of the micrometastatic foci of the invasive lobular carcinoma even many years after a successful treatment.

    The standard therapy is not yet established for the unresectable advanced gallbladder cancer (AGC). Here described is the outcome of authors' therapeutic protocol for AGC during the time Jan., 1989-Dec., 2008. Subjects are 73 patients (M 32/F 41, average age 65 y) with AGC of Stage IV. One shot arterial infusion (AI) of EEP regimen (etoposide (VP16)/4'epiadriamycin (EPIR)/cisplatin (CDDP)) is conducted via hepatic artery proper or common at the first angiography and one week later, external radiation therapy (RT), with about 30-50 Gy/6 fractions (actually, 12-61.6 Gy). AI is weekly done with FP regimen (CDDP/5-fluorouracil (FU)) through the reservoir indwelled in the gastroduodenal artery for 6 months where a metal stent for the stegnosis of bile duct is used if necessary after RT, and in recent days, additionally with biweekly CDDP/gemcitabin (GEM) regimen depending on patient's state after FP. As a result, RT is conducted to 62 cases (RT alone 8 cases), AI, 64 (alone, 10), and RT+AI, 54. Response is found to be 49% (CR 7 cases and PR, 28). Survivals 1- and 3-year are 39 and 6%, respectively, and average survival time, 408 days. Survival rate in (RT+AI) is significantly superior to that in AI alone and in RT alone. Prognosis in patients with jaundice, hepatic or duodenal invasion is significantly inferior to those without the symptom, and in non-responded cases, to responded cases. Complications like hepatic abscess are seen in 4 cases at 6 months after treatment. Four actual case-reports are presented in details with their images. Combination of RT+AI is suggested to be of utility for AGC, of which multi-center trial is awaited with addition of newer anti-cancers developed recently. (K.T.)

    Gallbladder agenesis (GBA) is extremely rare in dogs. To describe the history, clinical signs, diagnosis, treatment, and outcomes of dogs with GBA. Seventeen client-owned dogs with GBA. Medical records from 2006 through 2016 were retrospectively reviewed. Dogs were included when GBA was suspected on abdominal ultrasonography and confirmed by gross evaluation. Signalment, clinical signs, clinicopathological data, diagnostic imaging, histopathology, treatment, and outcome were recorded. Dogs were of 6 different breeds, and Chihuahuas (10 of 17) were most common. Median age at presentation was 1.9 (range, 0.7-7.4) years. Clinical signs included vomiting (5 of 17), anorexia (2 of 17), ascites (2 of 17), diarrhea (1 of 17), lethargy (1 of 17), and seizures (1 of 17). All dogs had increased serum activity of at least 1 liver enzyme, most commonly alanine aminotransferase (15 of 17). Fifteen dogs underwent computed tomography (CT) cholangiography; common bile duct (CBD) dilatation was confirmed in 12, without evidence of bile duct obstruction. Gross evaluation confirmed malformation of the liver lobes in 14 of 17 dogs and acquired portosystemic collaterals in 5 of 17. Ductal plate malformation was confirmed histologically in 16 of 17 dogs. During follow-up (range, 4-3,379 days), 16 of 17 dogs remained alive. Dogs with GBA exhibit clinicopathological signs of hepatobiliary injury and hepatic histopathological changes consistent with a ductal plate abnormality. Computed tomography cholangiography was superior to ultrasound examination in identifying accompanying nonobstructive CBD distention. Computed tomography cholangiography combined with laparoscopic liver biopsy is the preferable approach to characterize the full disease spectrum accompanying GBA in dogs.

    Full text: We performed a prospective study to determine frequency of presence of gallbladder varices (GBV) by intravenous CT portography (CTP) in patients with extrahepatic portal venous obstruction (EHPVO). 90 patients (age range: 2-55 years) with EHPVO (initially diagnosed on abdominal sonography) underwent CTP using a subsecond helical CT scanner. Axial overlapping sections of 2mm were obtained with collimation 3mm and table speed 4.5mm/sec (pitch 1.5). Presence and patterns of GBV were studied. CTP demonstrated GBV in 54 (60%) of 90 patients.GBV were said to be present when one or more of the following findings were seen: diffuse wall enhancement (26/90), pinpoint areas of enhancement in GB wall (33/90), obvious large collaterals in GB wall (8/90) and pericholecystic collaterals (49/90). Presence of GBV did not correlate with the site and extent of EHPVO. Contiguous intrahepatic collaterals extending from GB bed to intrahepatic portal vein branches were seen in 41 of 54 (76%) of patients with GBV, suggesting the role of GBV serving as bridging portoportal collaterals. Hepatic perfusion defects were seen in 5/54 patients with GBV and were not seen in remaining 36/90 patients of EHPVO. GB calculi were seen in only 4/54 cases with GBV (as determined on sonography) suggesting no increase in risk for cholelithiasis. GBV commonly develop as bridging collaterals in patients with EHPVO. CTP is very useful in detecting these varices and planning biliary surgery, given the frequency of iatrogenic surgical bleeding in these patients. Copyright (2002) Blackwell Science Pty Ltd

    2017-11-24

    We aimed to develop the first fully automated 3D gallbladder segmentation approach to perform volumetric analysis in volume data of magnetic resonance (MR) cholangiopancreatography (MRCP) sequences. Volumetric gallbladder analysis is performed for non-contrast-enhanced and secretin-enhanced MRCP sequences. Native and secretin-enhanced MRCP volume data were produced with a 1.5-T MR system. Images of coronal maximum intensity projections (MIP) are used to automatically compute 2D characteristic shape features of the gallbladder in the MIP images. A gallbladder shape space is generated to derive 3D gallbladder shape features, which are then combined with 2D gallbladder shape features in a support vector machine approach to detect gallbladder regions in MRCP volume data. A region-based level set approach is used for fine segmentation. Volumetric analysis is performed for both sequences to calculate gallbladder volume differences between both sequences. The approach presented achieves segmentation results with mean Dice coefficients of 0.917 in non-contrast-enhanced sequences and 0.904 in secretin-enhanced sequences. This is the first approach developed to detect and segment gallbladders in MR-based volume data automatically in both sequences. It can be used to perform gallbladder volume determination in epidemiological studies and to detect abnormal gallbladder volumes or shapes. The positive volume differences between both sequences may indicate the quantity of the pancreatobiliary reflux.

    Nucleolus is the most prominent subnuclear structure, which performs a wide variety of functions in the eu-karyotic cellular processes. In order to understand the structural and functional role of the nucleoli in bovine cells,we analyzed the proteomie composition of the bovine nueleoli. The nucleoli were isolated from Madin Darby bo-vine kidney cells and subjected to proteomie analysis by LC-MS/MS after fractionation by SDS-PAGE and strongcation exchange chromatography. Analysis of the data using the Mascot database search and the GPM databasesearch identified 311 proteins in the bovine nucleoli, which contained 22 proteins previously not identified in theproteomic analysis of human nucleoli. Analysis of the identified proteins using the GoMiner software suggestedthat the bovine nueleoli contained proteins involved in ribosomal biogenesis, cell cycle control, transcriptional,translational and post-translational regulation, transport, and structural organization.

    An 81-year-old man was referred to our institution for evaluation of high fever and a liver tumor that had been detected by ultrasonography. Computed tomography revealed a low-density mass with peripheral ring-like enhancement in S5 of the liver. The liver mass was in contact with the gallbladder, and the boundary between the mass and the gallbladder was unclear. On the suspicion of liver abscess, percutaneous transhepatic drainage was performed. The cavity of the abscess communicated with the gallbladder. Because the cavity had no tendency to reduce in size, we performed surgical resection under a preoperative diagnosis of liver abscess or primary liver carcinoma invading to the gallbladder. Intraoperative findings revealed a liver tumor invading the transverse colon and gallbladder. Subsegmentectomy of S4a and S5 of the liver combined with gallbladder and transverse colon resection was performed. Histopathological findings indicated the growth of a mass forming type intrahepatic cholangiocarcinoma with invasion to the transverse colon and gallbladder, and the pathological stage of the tumor was pT3N0M0, fStage Ⅲ. Thus far, the patient is alive without recurrence 9 months after surgery. Here, we report an extremely rare case of intrahepatic cholangiocarcinoma that invaded other organs and was associated with an intra-tumor abscess.

    Full Text Available BACKGROUND: Helicobacter pylori has been isolated from 10%-20% of human chronic cholecystitis specimens but the characteristics of "Helicobacter pylori positive cholecystitis" remains unclear. This study aims to compare the clinicopathological features between chronic cholecystitis patients with and without Helicobacter pylori infection in gallbladder mucosa. METHODS: Three hundred and twenty-six chronic cholecystitis patients were divided into two groups according to whether Helicobacter pylori could be detected by culture, staining or PCR for Helicobacter 16s rRNA gene in gallbladder mucosa. Positive samples were sequenced for Helicobacter pylori-specific identification. Clinical parameters as well as pathological characteristics including some premalignant lesions and the expression levels of iNOS and ROS in gallbladder were compared between the two groups. RESULTS: Helicobacter pylori infection in gallbladder mucosa was detected in 20.55% of cholecystitis patients. These patients had a higher prevalence of acid regurgitation symptoms (p = 0.001, more histories of chronic gastritis (p = 0.005, gastric ulcer (p = 0.042, duodenal ulcer (p = 0.026 and higher presence of Helicobacter pylori in the stomach as compared to patients without Helicobacter pylori infection in the gallbladder mucosa. Helicobacter pylori 16s rRNA in gallbladder and gastric-duodenal mucosa from the same individual patient had identical sequences. Also, higher incidences of adenomyomatosis (p = 0.012, metaplasia (p = 0.022 and higher enhanced expressions of iNOS and ROS were detected in Helicobacter pylori infected gallbladder mucosa (p<0.05. CONCLUSIONS: Helicobacter pylori infection in gallbladder mucosa is strongly associated with Helicobacter pylori existed in stomach. Helicobacter pylori is also correlated with gallbladder premalignant lesions including metaplasia and adenomyomatosis. The potential mechanism might be related with higher ROS

    To gain insight to underlying mechanism of the formation of calcium carbonate (CaCO 3 ) gallbladder stones, we did comparative study of stones with mud appearance and those with coralliform appearance. A total of 93 gallbladder stones with mud appearance and 50 stones with coralliform appearance were analyzed. The appearance, color, texture, and the detection of Clonorchis sinensis eggs by microscopic examination were compared between the two groups. Then, the material compositions of stones were analyzed using Fourier Transform Infrared spectroscopy and the spectrogram characteristics were compared. Moreover, microstructure characteristics of the two kinds of stones were observed and compared with Scanning Electron Microscopy. Mud-like gallbladder stones were mainly earthy yellow or brown with brittle or soft texture, while coralliform stones were mainly black with extremely hard texture, the differences between the two groups was significant (p mud-like gallbladder stones were CaCO 3 stones, and mainly aragonite; while all of the coralliform stones were CaCO 3 stones, and mainly calcite (p mud-like CaCO 3 stones was lower than that in coralliform CaCO 3 stones (p Mud-like CaCO 3 stones mainly happened to patients with cystic duct obstruction. Clonorchis sinensis infection was mainly associated with coralliform (calcite) CaCO 3 stones. Cystic duct obstruction was mainly associated with mud-like (aragonite) CaCO 3 stones. © 2017 Wiley Periodicals, Inc.

    Introduction: Gallbladder volvulus (GV), or torsion of the gallbladder, is an uncommon surgical emergency. This article reviews the world literature related to GV. We examine the history of gallbladder torsion and highlight the critical constellation of presenting signs and symptoms, which guide the acute care physician and surgeon to accurate and timely diagnosis of GV before surgical intervention. Methods: A comprehensive review of all published cases of GV was performed using the National Library of Medicine (PubMed) database. Results: Lists of typical symptoms and clinical presentations are provided to allow clinicians to establish an accurate preoperative diagnosis. Conclusion: GV is frequently undiagnosed before surgical intervention. However, clinical presentation and associated radiographic findings can lead to an accurate diagnosis if the clinician is aware of this uncommon condition. When the diagnosis has been established before operative intervention, expeditious laparoscopic cholecystectomy can be performed safely. Delays in diagnosis may mandate open cholecystectomy if laparoscopic extraction is contraindicated because of undesirable sequelae of gallbladder necrosis, specifically perforation, bilious peritonitis, and hemodynamic instability.

    The aim of the present study was to elucidate the mechanisms of development of cholesterol crystals and gallstones during weight reduction in obese subjects. Twenty-five morbidly obese, gallstone-free subjects underwent vertical-banded gastroplasty. Gallbladder bile was collected at the time of the operation via needle aspiration and 1.1-7.3 months after the operation via ultrasound-guided transhepatic puncture of the gallbladder. The mean weight loss was 17 kg. Two patients developed gallstones and 10 patients displayed cholesterol crystals in their bile. In patients with a follow-up time of less than 2 months (n = 13), cholesterol saturation increased from 90% to 114% but tended to decrease in the patients with a follow-up time of more than 2 months. The extraction of the concanavalin-A-binding fraction from gallbladder bile obtained after weight reduction in 7 patients prolonged crystallization detection time from 6 to 10 days. The hexosamine concentration, a marker for mucin, was increased by about 100% in bile obtained in 6 of 7 patients after weight reduction. In conclusion, the results indicate that crystallization-promoting compounds (mucin) are of great importance in the development of cholesterol crystals and gallstones in obese subjects during weight reduction, probably because of defective gallbladder emptying.

    The surgical treatment of diseases of the gall-bladder consists largely of the treatment of stones and their complications. There is a voluminous literature on gallstones, but its analysis would serve little purpose in this paper. It is of greater value to analyse one's own experience, to discuss how we can diagnose lesions of.

    Actinomycosis should be included in the differential diagnosis when sonography and computed tomography findings show a mass engulfing the stone in the gallbladder and extensive pericholecystic infiltration with extension to neighboring abdominal wall muscle. A ctinomycosis is a chronic suppurative and granulomatous disease that is characterized by the formation of multiple abscesses, draining sinuses, abundant granulation and dense fibrous tissue. The disease is most frequently caused by Actinomyces israelii. These organisms are gram-positive anaerobic bacteria, and are considered opportunistic pathogens associated with infection, trauma or surgery. These events allow them to cross mucosal barriers as these organisms are normally present in healthy individuals, especially in the oral cavity, gastrointestinal tract, and female genital tract. In abdominopelvic actinomycosis, aggressive perilesional infiltration with a tendency to cross fascial planes or boundaries and extend to the abdominal wall has been well described as an important radiologic finding. Actinomycosis of the gallbladder is an extremely rare disease; only 21 cases have been reported in the English literature. Moreover, a diagnosis of actinomycosis of the gallbladder is difficult because this condition can be confused with carcinoma. We report here on a rare case of actinomycosis of the gallbladder that presented as a mass by sonography and computed tomography (CT)

    Risk factors for gallbladder cancer (GBC) except gallstones are not well known. The objective was to study the risk factors for GBC. In a case-control study, 200 patients with GBC, 200 healthy controls and 200 gallstones patients as diseased controls were included prospectively. The risk factors studied were related to socioeconomic profile, life style, reproduction, diet and bile acids. On comparing GBC patients (mean age 51.7 years; 130 females) with healthy controls, risk factors were chemical exposure [odd ratios (OR): 7.0 (2.7-18.2); p < 0.001)], family history of gallstones [OR: 5.3 (1.5-18.9); p < 0.01)], tobacco [OR: 4.1 (1.8-9.7); p < 0.001)], fried foods [OR: 3.1 (1.7-5.6); p < 0.001], joint family [OR: 3.2 (1.7-6.2); p < 0.001], long interval between meals [OR: 1.4 (1.2-1.6); p < 0.001] and residence in Gangetic belt [OR: 3.3 (1.8-6.2); p < 0.001]. On comparing GBC cases with gallstone controls, risk factors were female gender [OR: 2.4 (1.3-4.3); p = 0.004], residence in Gangetic belt [OR: 2.3 (1.2-4.4); p = 0.012], fried foods [OR: 2.5 (1.4-4.4); p < 0.001], diabetes [OR: 2.7 (1.2-6.4); p = 0.02)], tobacco [OR 3.8 (1.7-8.1); p < 0.001)] and joint family [OR: 2.1 (1.2-3.4); p = 0.004]. The ratio of secondary to primary bile acids was significantly higher in GBC cases than gallstone controls (20.8 vs. 0.44). Fried foods, tobacco, chemical exposure, family history of gallstones, residence in Gangetic belt and secondary bile acids were significant risk factors for GBC. Copyright © 2012 UICC.

    Objective: To evaluate the feasibility and safety of a new style of Laparoscope and Endoscope Cooperative gallbladderpreserving Surgery (LECS), an improved method of minimally invasive gallbladder-preserving polypectomy. Study Design: An experimental study. Place and Duration of Study: Department of General Surgery, The Second Affiliated Hospital of Soochow University, China, from January 2009 to July 2013. Methodology: Clinical data of patients subjected to LECS and Laparoscopic Cholecystectomy (LC) was analysed. The inclusion criteria were normal size clear gallbladder bile with total volume (FV) of the gallbladder = 15 - 25 ml, the Residual Volume (RV) = 5 ml, and the Emptying Figure (EF) > 75 percentage, with polyps diagnosed definitively by B-type ultrasonic imaging or CT desirous of preserving gallbladder. Exclusion criteria were a history of midsection surgery, serious diseases of any organ, hepatic injury, or coagulation disturbance. Mean hospital stay and complications were also noted. Independent sample t-test, the frequency comparison used chi-square test (N > 5), and Fisher's exact test (N < 5) were used for statistical test. Results: The mean hospital stay after LECS was 3.50 ± 0.31 days, and 3.50 ± 0.31 days for the LC group. The mean age in LC and LECS group was 50 ± 25.4 and 44 ± 12.1 years, respectively. Complications after operation in the LECS were indigestion and diarrhea; LC group had indigestion (9.33 percentage), diarrhea (10.67 percentage), and gastroesophageal reflux (6.6.7 percentage). In the 3 months follow-up after discharging from the hospital, no patient had recurrence of any gallbladder disease; at 1 year follow-up, 1 patient (1.28 percentage) developed cholesterol crystals; at 3-year follow-up, 3 cases (3.84 percentage) were found to have recurring polyps (2-4 pieces), and 2 (2.56 percentage) patients developed cholesterol crystals. Conclusion: Minimally invasive gallbladder-preserving polypectomy which used a CHIAO

  16. Qualitative metabolomics profiling of serum and bile from dogs with gallbladder mucocele formation

    Mucocele formation is characterized by secretion of abnormally thick mucus by the gallbladder epithelium of dogs that may cause obstruction of the bile duct or rupture of the gallbladder. The disease is increasingly recognized and is associated with a high morbidity and mortality. The cause of gallbladder mucocele formation in dogs is unknown. There is a strong breed predisposition and affected dogs have a high incidence of concurrent endocrinopathy or hyperlipidemia. These observations suggest a significant influence of both genetic and metabolic factors on disease pathogenesis. In this study, we investigated a theory that mucocele formation is associated with a syndrome of metabolic disruption. We surmised that a global, untargeted metabolomics approach could provide unique insight into the systemic pathogenesis of gallbladder mucocele formation and identify specific compounds as candidate biomarkers or treatment targets. Moreover, concurrent examination of the serum and hepatic duct bile metabolome would enable the construction of mechanism-based theories or identification of specific compounds responsible for altered function of the gallbladder epithelium. Abnormalities observed in dogs with gallbladder mucocele formation, including a 33-fold decrease in serum adenosine 5’-monophosphate (AMP), lower quantities of precursors required for synthesis of energy transporting nucleotides, and increases in citric acid cycle intermediates, suggest excess metabolic energy and a carbon surplus. Altered quantities of compounds involved in protein translation and RNA turnover, together with accumulation of gamma-glutamylated and N-acetylated amino acids in serum suggest abnormal regulation of protein and amino acid metabolism. Increases in lathosterol and 7α-hydroxycholesterol suggest a primary increase in cholesterol synthesis and diversion to bile acid formation. A number of specific biomarker compounds were identified for their ability to distinguish between control

    Full Text Available Choledochal cyst is a relatively rare condition. Even rarer is a choledochal cyst in association with a gallbladder carcinoma. This study reports a rare case of gallbladder carcinoma coexisting with a choledochal cyst in a Nigerian patient. Clinical records of the patient including preoperative evaluation, intraoperative findings, and postoperative care were reviewed. A 38-year-old woman presented with the recurrent right upper abdominal pain of 3 years duration associated with progressive weight loss, anorexia, recurrent vomiting, as well as, low-grade fever with chills and rigors. Physical examination revealed an anicteric woman with tenderness in the right hypochondrium and a positive Murphy's sign. A combination of abdominal ultrasound and computed tomography scan suggested a Type IV choledochal cyst and a distended gallbladder with thickened walls containing a heterogeneous hyperdense mass. Preoperative serum alkaline phosphatase was elevated while endoscopic retrograde cholangiopancreatography was inconclusive. At laparotomy, extrahepatic biliary dilatation and enlarged, the nodular gallbladder was found with a diffusely fibrotic pancreas. Intraoperative cholangiogram confirmed Type IV choledochal cyst. Excision of the common bile duct and radical cholecystectomy was performed, and a Roux-en-Y hepaticojejunostomy. Histopathology confirmed the diagnosis of gallbladder adenocarcinoma. She had adjuvant chemotherapy and is presently on follow-up. No evidence of recurrence after 5 years of follow-up. A high index of suspicion is required to detect a combination of these two rare entities. When detected, both conditions should be surgically addressed at the same sitting, and when combined with adjuvant chemotherapy, may increase the chances of achieving a cure.

  18. Rapid formation of cholesterol crystals in gallbladder bile is associated with stone recurrence after laparoscopic cholecystotomy.

    Laparoscopic cholecystotomy (LCT) with subsequent extraction of gallstones and primary closure of the gallbladder has been introduced as an alternative therapy for patients with cholecystolithiasis and preserved gallbladder function. However, stone recurrence has to be considered as a major drawback that might be related to lithogenic factors of gallbladder bile or the composition of gallbladder stones. Therefore, these were studied in relation to stone recurrence within an observation period of 1 to 5 years (median, 3.6 years) in 50 patients after LCT. The concentrations of total and individual bile acids, phospholipids, cholesterol, total lipids, mucin, protein, and the cholesterol saturation indices in gallbladder bile were not significantly different between 10 patients with and 40 patients without stone recurrence. However, the crystal observation time was significantly (P < .02) shorter (range, 1-2 days; median, 1.5) in the bile of patients with stone recurrence compared to those without (range, 1-21 days, median 3.5). Moreover, all 10 stone recurrences were observed in the 28 patients with a crystal observation time in the bile of less than or equal to 2 days (approximate annual risk: 12%-15%), and no recurrences were observed in the 22 patients with a crystal observation time greater than 2 days (P < .0001) or in patients with pigment stones. The rapid formation of cholesterol monohydrate crystals in bile seems to be the major risk factor for recurrent stones after LCT. These are most likely cholesterol stones and, therefore, are amenable to oral bile-acid prevention or treatment.

    Cystoisospora belli, previously known as Isospora belli, is an obligate intracellular coccidian parasite that is most often associated with gastrointestinal disease in immunocompromised patients. In this study, we detail the clinicopathologic features of 18 cases of Cystoisospora infection affecting the gallbladder in immunocompetent individuals and compare them with a control group. Each case was reviewed for cholecystitis (none, acute, chronic), epithelial disarray, presence of intraepithelial lymphocytes (none, rare [≤5 per 20 epithelial cells], present [>5 per 20 epithelial cells]), architectural distortion, intramucosal eosinophilia, and mural thickening/serositis. The mean age of patients with Cystoisospora infection was 33 years and the male to female ratio 1:4.3. Cholecystectomy was performed for biliary dyskinesia (n=7), abdominal pain (n=7), suspected cholelithiasis (n=5), and cholecystitis (n=3). In 2 cases, Cystoisospora was found in donor gallbladders resected at the time of liver transplantation. Each case was characterized by eosinophilic, oval or banana-shaped intraepithelial parasites within perinuclear parasitophorous vacuoles. Most cases showed epithelial disarray and minimal intraepithelial lymphocytosis. Of the 11 cases with an average follow-up of 15 months, none had evidence of disease related to Cystoisospora infection within the biliary tract or elsewhere in the gastrointestinal tract. We present the largest series of gallbladder cystoisosporiasis in immunocompetent patients to date. Cystoisospora infection is underrecognized in the gallbladders of immunocompetent patients, in part due to the subtle findings in routine cholecystectomy specimens. On the basis of the clinical follow-up, gallbladder cystoisosporiasis in immunocompetent individuals appears to be a self-limited infection.

    Full Text Available This study was designed to determine the occurrence and topographical distribution of galanin-like immunoreactivity (GAL-LI in the porcine gallbladder and sphincter of Oddi and to investigate the pharmacologic effect of GAL on gallbladder and sphincter of Oddi motility. By radioimmunoassay the concentration of GAL-LI in the gallbladder was 2.75 ± 0.23, 9.73 ± 1.33 in the common bile duct and 5.10 ± 0.37 in the sphincter of Oddi (pmol/g ± SE. By immunohistochemistry GAL-LI was found exclusively in ganglionic cells and in nerve fibers among the smooth muscle bundles. Gallbladder and sphincter of Oddi pressures were recorded before and during 5-minute local intraarterial infusion of 4, 8, 19, 39, 78 and 194 ng GAL-Kg-1-min-1 in 12 anaesthetized pigs. GAL in doses ≥ 39 ng.kg-1.min-1 significantly reduced sphincter of Oddi phasic wave frequency (4.8 ± 0.4 vs. 2.1 ± 0.5; p = 0.004 and sphincter of Oddi motility index (70.2 ± 6.02 vs. 27.7 ± 8.3; p = 0.002 but did not affect gallbladder pressure. We conclude that the distribution of GAL-LI in the sphincter of Oddi and the effect that a pharmacologic dose of GAL has on sphincter of Oddi motor activity, suggests that GAL may be involved in the physiologic control of bile flow in the pig.

    Tc-99m HIDA cholescintigraphy is the diagnostic procedure of choice for acute cholecystitis. Acute cholecystitis is associated in vast majority of the cases with cystic duct obstruction. The demonstration of presence (cystic duct patency) or absence (cystic duct obstruction) of visualization of the gallbladder on cholescintigraphy is critical to the diagnosis of acute cholecystitis. The visualization of the gallbladder rules out acute cholecystitis in most of the cases. Although, in most cases, determination of visualization or nonvisualization of gallbladder is straight forward, occasionally it can be challenging. We describe a patient with suspected acute cholecystitis, in whom an unusual appearance of the gallbladder on hepatobiliary scintigraphy was clarified with SPECT/CT, an approach that is rarely used in Tc-99m HIDA cholescintigraphy.

    Gallbladder cancer (GBC) is an uncommon neoplasm in the United States, but one with high mortality rates. This malignancy remains largely understudied at the molecular level such that few targeted therapies or predictive biomarkers exist. We built the first series of serial analysis of gene expression (SAGE) libraries from GBC and nonneoplastic gallbladder mucosa, composed of 21-bp long-SAGE tags. SAGE libraries were generated from three stage-matched GBC patients (representing Hispanic/Latino, Native American, and Caucasian ethnicities, respectively) and one histologically alithiasic gallbladder. Real-time quantitative PCR was done on microdissected epithelium from five matched GBC and corresponding nonneoplastic gallbladder mucosa. Immunohistochemical analysis was done on a panel of 182 archival GBC in high-throughput tissue microarray format. SAGE tags corresponding to connective tissue growth factor (CTGF) transcripts were identified as differentially overexpressed in all pairwise comparisons of GBC (P Cancer Genome Anatomy Project web site and should facilitate much needed research into this lethal neoplasm.

    Cholelithiasis is a very common disease in the United States. Most cases remain asymptomatic but a fraction of these patients can develop serious complications such as cholecystitis which may lead to gallbladder perforation and gallbladder cancer which is much less common. Here, we present three cases of cholelithiasis where transthoracic echocardiography was performed routinely. In each case, echocardiography detected cholelithiasis which prompted three-dimensional (3D) echocardiographic evaluation. Three-dimensional echocardiography allowed for more comprehensive examination of the gallbladder shape, size, and wall thickening and the measurement and composition of the stones in three dimensions, measurement of stone volumes, and minimized shadowing produced by stone calcifications. These cases suggest that routine echocardiography has value in detecting gallstones and that 3D echocardiography has incremental value over two-dimensional echocardiography due to pyramidal data sets which allow sequential slicing through the gallbladder and full gallbladder examination without a technologist who is trained in gallbladder imaging. These pyramidal data sets can be further viewed and cropped by a radiologist specialized in abdominal ultrasound. © 2012, Wiley Periodicals, Inc.

    Although well studied the association between chronic typhoid carrier state and carcinoma of the gallbladder (CaGB) remains unproven. The study was performed at a tertiary care medical center in North India and involved 52 patients with CaGB, 223 patients with benign gallbladder diseases, 508 healthy individuals and, 424 corpses. For the detection of Salmonella enterica serovar Typhi, hepatobiliary specimens were subjected to DNA extraction for specific nested- PCR amplification of the S. Typhi flagellin gene. Anti-Vi S. Typhi antibodies were detected in serum samples from patients by indirect haemagglutination. Thirty five of the 52 (67.3%) CaGB patients were PCR-positive for the S. Typhi flagellin gene; significantly higher than for patients with benign gallbladder diseases (95/223, 42.6%; p or = 160) in their serum were 20/52 (38.5%) for CaGB patients, 31/223 (13.9%) for patients with benign gallbladder diseases, and 47/508 (9.2%) for healthy individuals. Specific nested-PCR amplification of the S. Typhi flagellin gene in hepato-biliary specimens was more sensitive for detection of S. Typhi carriage than anti-Vi antibody titres in serum. The results demonstrate an association between typhoid carriage and gallbladder diseases, both CaGB and benign. S. Typhi specific immunosuppression is also suggested in patients with gallbladder diseases.

    Full Text Available Bovine tuberculosis is caused by the infection of Mycobacterium tuberculosis var. bovis (M. bovis. This species is one of Mycobacterium tuberculosis complex, can infect wide range of hosts: cattle and other domesticated animals, wild mammals and humans (zoonotic. M. bovis bacterium from infected hosts can be transmitted to other susceptible animals and humans through respiratory excretes and secretion materials. Humans can be infected with M. bovis by ingested M. bovis contaminated animal products, unpasteurised milk from tuberculosis cows or through respiratory route of contaminated aerosol. Bovine tuberculosis at the first stage does not show any clinical sign but as the disease progress in the next stage which may take several months or years, clinical signs may arise, suh as: fluctuative body temperature, anorexia, lost body weight, coughing, oedema of lymph nodes, increased respiratory frequencies. Pathological lesion of bovine tuberculosis is characterised by the formation of granulomas (tubercles, in which bacterial cells have been localised, most in lymph nodes and pulmonum, but can occur in other organs. The granulomas usually arise in small nodules or tubercles appear yellowish either caseus, caseo-calcareus or calcified. In Indonesia, bovine tuberculosis occurred in dairy cattle since 1905 through the imported dairy cows from Holland and Australian. It was unfortunate that until recently, there were not many research and surveilances of bovine tuberculosis conducted in this country, so the distribution of bovine tuberculosis is unknown. Early serological diagnosis can be done on live cattle by means of tuberculin tests under field conditions. Confirmation can be done by isolation and identification of excreted and secreted samples from the slaughter house. Antibiotic treatment and vaccination were uneffective, therefore the effective control of bovine tuberculosis is suggested by tuberculin tests and by slaughtering the selected

    Laparoscopic cholecystectomy has become the standard treatment for gallbladder diseases. However, there are still some patients for whom conversion to open surgery is required. This surgery can produce significant post-operative pain. Opioids drugs have traditionally been used to treat this pain, but side effects have led to seeking alternatives (plexus, nerve or fascia blocks or wound). The cases are presented of 4 patients subjected to ultrasound-guided intercostal branches blocks in the mid-axillary line from T6 to T12 with levobupivacaine as an analgesic alternative in open surgery of gallbladder, with satisfactory results.

    In three models of cholelithiasis (dihydrocholesterol-fed rabbits, cholesterol-cholic acid-fed mice, and Lincomycin-treated guinea pigs), the quantity and chemical composition of gallbladder epithelial mucin have been studied using (1) a spectrum of histochemical glycoprotein stains, and (2) biochemical extraction, purification and analysis of the carbohydrate components of epithelial mucin. Despite the diverse mechanism of stone induction and difference in stone composition, a common pattern of response by the epithelial mucin was observed in all three models. There was a quantitative increase in epithelial mucus production at a time before stones were formed and this increase persisted till stones were formed. There was no difference, qualitatively, between mucus produced by normal and stone-forming gallbladders.

    BACKGROUND: Visceral pain is characterized by poor pain localization and a referred or radiating pain pattern. Its clinical importance in the abdomen is stressed by the finding that about one-third of patients still complain of abdominal pain after cholecystectomy. A better understanding...... were performed. After each injection of saline the localization of pain and the presence of nausea and vomiting were registered. The injections continued until the patient felt abdominal pain necessitating cessation of the investigation or until the cystic duct opened (visualized on cholescintigraphy......). RESULTS: Distension of the gallbladder caused pain in 10 of the 12 patients. In 70% the pain was localized under the right costal margin or in the epigastrium. No mathematical formula could describe the pressure-volume relation in the gallbladder. The cystic duct opening pressure varied between 3 and 44...

    Pancreatic agenesis is an extremely rare cause of neonatal diabetes mellitus and has enabled the discovery of several key transcription factors essential for normal pancreas and beta cell development. We report a case of a Caucasian female with complete pancreatic agenesis occurring together with semilobar holoprosencephaly (HPE), a more common brain developmental disorder. Clinical findings were later confirmed by autopsy, which also identified agenesis of the gallbladder. Although the sequences of a selected set of genes related to pancreas agenesis or HPE were wild-type, the patient's phenotype suggests a genetic defect that emerges early in embryonic development of brain, gallbladder and pancreas. Developmental defects of the pancreas and brain can occur together. Identifying the genetic defect may identify a novel key regulator in beta cell development.

    Emptying of the gallbladder was studied by the simultaneous use of 99m Tc-labelled diethyl-iminodiacetic acid (HIDA) scanning and real-time ultrasonography. In response to a liquid test meal the gallbladder volume was reduced for 80 min and then increased again, but the radionuclide evacuation continued and was more complete than could be explained by the reduction of gallbladder volume. In response to intravenous infusion of cholecystokinin, a maximal contraction of the gallbladder to 35% of the basal volume was obtained at 40 min, and 36% of the HIDA then remained in the gallbladder. In a separate series repeated intravenous injections of 99m Tc-HIDA were given after the test meal, and the isotope was found to enter the gallbladder even when the gallbladder contracted. The results support the view that the gallbladder acts like a ''bellows'' when contracting and that postprandial fluid secretion by the gallbladder mucosa may help to evacuate its contents. 11 refs., 4 figs

    Objective: To evaluate the diagnostic value about the dilated extent of bile duct and gallbladder in low biliary obstructive diseases. Methods: CT and ERCP findings of 105 patients with low biliary obstructive disease were retrospectively analyzed. The dilated extent of intrahepatic and extra- hepatic bile duct and gallbladder were classified into seven types: Type I: severe dilatation of intrahepatic and extrahepatic bile duct and gallbladder; Type II: severe dilatation of extrahepatic bile duct and gallbladder and slight dilated intrahapetic bile duct; Type III: severe dilatation of intrahepatic and extrahepatic bile duct without or slight dilatation of gallbladder; Type IV: severe extrahepatic bile duct dilatation without or slight dilatation of intrahepatic bile duct and gallbladder; Type V: severe intrahepatic bile duct dilatation without or with slight dilatation of extrahepatic bile duct and gallbladder; Type VI: severe gallbladder dilatation without or with slight intrahepatic and extra- hepatic bile duct dilatation; Type VII: without or with slight dilatation of intrahepatic and extrahepatic bile duct and gallbladder. The biliary system dilated extent of low biliary obstructive disease on CT and ERCP were compared with results of clinical, operation, and pathology. Results: Thirty-three cases of tumor and 72 cases of non-tumor were proved by clinical and operation in 105 patients with low biliary obstructive disease. In 33 tumor patients, 16 patients were identified as Type I, 10 patients Type II, 4 patients Type III, 1 patient Type IV, 2 patients Type VII. In 72 non-tumor patients, 4 patients were identified as Type I, 4 patients Type II, 9 patients Type III, 33 patients Type IV, 2 patients Type V, 11 patients Type VI, 19 patients Type VII. A large difference between I, II type and III-VII type biliary dilatation existed in tumor and non-tumor group (χ 2 =47.33, P<0.01). Conclusion:Low obstructive biliary diseases are closely correlated with the dilated

    Jaundice as a presenting symptom of gallbladder cancer has traditionally been considered to be a sign of advanced disease, inoperability, and poor outcome. However, recent studies have demonstrated that a small subset of these patients can undergo resection with curative intent. Patients with gallbladder cancer managed surgically from 2000 to 2014 in 10 US academic institutions were stratified based on the presence of jaundice at presentation (defined as bilirubin ≥4 mg/ml or requiring preoperative biliary drainage). Perioperative morbidity, mortality, and overall survival were compared between jaundiced and non-jaundiced patients. Of 400 gallbladder cancer patients with available preoperative data, 108 (27%) presented with jaundice while 292 (73%) did not. The fraction of patients who eventually underwent curative-intent resection was much lower in the presence of jaundice (n = 33, 30%) than not (n = 218, 75%; P Jaundiced patients experienced higher perioperative morbidity (69 vs. 38%; P = 0.002), including a much higher need for reoperation (12 vs. 1%; P = 0.003). However, 90-day mortality (6.5 vs. 3.6%; P = 0.35) was not significantly higher. Overall survival after resection was worse in jaundiced patients (median 14 vs. 32 months; P jaundiced patients revealed a more favorable survival after resection in the presence of low CA19-9 Jaundice is a powerful preoperative clinical sign of inoperability and poor outcome among gallbladder cancer patients. However, some of these patients may still achieve long-term survival after resection, especially when preoperative CA19-9 levels are low and no lymphovascular invasion is noted pathologically.

    Purpose Although adjuvant chemoradiotherapy for resected gallbladder cancer may improve survival for some patients, identifying which patients will benefit remains challenging because of the rarity of this disease. The specific aim of this study was to create a decision aid to help make individualized estimates of the potential survival benefit of adjuvant chemoradiotherapy for patients with resected gallbladder cancer. Methods Patients with resected gallbladder cancer were selected from the Surveillance, Epidemiology, and End Results (SEER) –Medicare database who were diagnosed between 1995 and 2005. Covariates included age, race, sex, stage, and receipt of adjuvant chemotherapy or chemoradiotherapy (CRT). Propensity score weighting was used to balance covariates between treated and untreated groups. Several types of multivariate survival regression models were constructed and compared, including Cox proportional hazards, Weibull, exponential, log-logistic, and lognormal models. Model performance was compared using the Akaike information criterion. The primary end point was overall survival with or without adjuvant chemotherapy or CRT. Results A total of 1,137 patients met the inclusion criteria for the study. The lognormal survival model showed the best performance. A Web browser–based nomogram was built from this model to make individualized estimates of survival. The model predicts that certain subsets of patients with at least T2 or N1 disease will gain a survival benefit from adjuvant CRT, and the magnitude of benefit for an individual patient can vary. Conclusion A nomogram built from a parametric survival model from the SEER-Medicare database can be used as a decision aid to predict which gallbladder patients may benefit from adjuvant CRT.

    A male Pickwickian syndrome patient was admitted to the hospital with sudden onset of abdominal pain. Physical examination was equivocal. Due to patient's ileus and morbid obesity (weight 450 lb), neither TCT scan nor ultrasound was possible. A Tc-99m PIPIDA hepatobiliary imaging study revealed intraperitoneal leakage of radioactive bile with collection of the activity in both abdominal gutters, indicating gallbladder rupture. Prompt surgery confirmed the diagnosis

    Gallstone is a high-risk factor for gallbladder pre-malignancy or malignancy (GB PM-M) but which substances of gallstones definitely assist to turn out in to GB PM-M, remains unclear. This study aimed to find out the presence of carcinogenic heavy metals in gallstones and to explore the aetiopathogenesis of gallbladder pre-malignancy and malignancy. Presence of elements in gallstones was detected by energy dispersive X-ray spectroscopy (EDS) with scanning electron microscopy (SEM) and then level of carcinogenic heavy metals was estimated in gallstones using atomic absorption spectroscopy (AAS). The experiment was carried out in gallstone samples of 46 patients with gallbladder pre-malignant and malignant condition (PM-M group) and 65 sex and age-matched patients with chronic cholecystitis (C-C group). Gallstones were also classified in to three types such as cholesterol stone, mixed stone, and black pigment stone. EDS analysis detected presence of mercury, lead, and cobalt elements in all types of gallstones of both PM-M and C-C groups. AAS analysis revealed significantly higher amount of mercury (p heavy metals also varied among stone types of both groups. EDS phase analysis showed 'dense deposits' of these metals in gallstones. Presence of significantly higher amount of mercury, lead, cobalt, and cadmium in gallstones may play a pivotal role as risk factors in the development of gallbladder malignancy or pre-malignancy. 'Dense deposits' of these metals in the gallstones which is the first observation, may act as crucial doses of carcinogens.

    1. Bile salts stimulate mucin secretion by the gallbladder epithelium. We have investigated whether this stimulatory effect is due to a detergent effect of bile salts. 2. The bile salts taurocholic acid (TC) and tauroursodeoxycholic acid (TUDC) and the detergents Triton X-100 (12.5-400 microM) and Tween-20 (0.1-3.2 mM) were applied to monolayers of cultured dog gallbladder epithelial cells. Mucin secretion was studied by measuring the secretion of [3H]N-acetyl-d-glucosamine-labelled glycoproteins. We also attempted to alter the fluidity of the apical membrane of the cells through extraction of cholesterol with beta-cyclodextrin (2.5-15 mM). The effect on TUDC-induced mucin secretion was studied. Cell viability was assessed by measuring lactate dehydrogenase (LDH) leakage or 51Cr release. 3. In contrast with the bile salts, the detergents were not able to cause an increase in mucin secretion without causing concomitant cell lysis. Concentrations of detergent that increased mucin release (>100 microM Triton X-100, >0.8 mM Tween-20), caused increased LDH release. Incubation with beta-cyclodextrin resulted in effective extraction of cholesterol without causing an increase in 51Cr release. However, no effect of the presumed altered membrane fluidity on TUDC (10 mM)-induced mucin secretion was observed. 4. The stimulatory effect of bile salts on mucin secretion by gallbladder epithelial cells is not affected by the fluidity of the apical membrane of the cells and also cannot be mimicked by other detergents. We conclude that the ability of bile salts to cause mucin secretion by the gallbladder epithelium is not determined by their detergent properties.

    To study the movement along the gut and the effect upon the gallbladder volume of alcoholic beverages taken in the interdigestive state. The study comprised three research blocks attended by 12 healthy subjects each. Within a given research block volunteers underwent three examination sessions held on separate days, being offered an alcoholic beverage, or an aqueous ethanol solution of an identical proof, or a corresponding volume of isotonic glucose solution; the order of administration of the drinks was randomized. The beverages tested were: beer (4.7% vol, 400 ml), red wine (13.7% vol, 200 ml), whisky (43.5% vol, 100 ml) within the "Beer", "Wine", and "Whisky" research block, respectively. Gastric myoelectrical activity was examined electrogastrographically, gastric emptying with ¹³C-sodium acetate breath test, orocaecal transit with lactulose H₂ breath test, gallbladder emptying with ultrasonography, breath ethanol with alcotest. The study showed that alcoholic beverages were emptied from the stomach significantly slower than isotonic glucose. Alcoholic beverages produced by fermentation only (beer, red wine) were emptied from the stomach more slowly than ethanol solutions of identical proof, while gastric evacuation of whisky (distillation product) and matching alcohol solution was similar. The slower gastric evacuation of alcoholic beverages and ethanol solutions could not be ascribed to a disorganization of the gastric myoelectrical activity. The orocaecal transit of beer and red wine did not differ from that of isotonic glucose, whereas the orocaecal transit of whisky and high proof ethanol was markedly prolonged. Red wine and whisky, and to a similar extent control ethanol solutions caused an inhibition and delay of gallbladder emptying. We concluded that alcoholic beverages taken on an empty stomach exert a suppressive effect upon the transport function of the digestive tract and gallbladder emptying. The extent of this action depends on the type of a

    Imaging Efficiency was analyzed in 118 cases of benign lesion, including adenoma and 36 cases of malignant lesion without lymph node metastasis (Stage I) of 154 cases histologically diagnosed as elevated lesions of the gallbladder (443 lesions). On ultrasonography, the maximum diameter of the benign lesions, except in the case of adenomyomatosis, was 17 mm; the minimum diameter in the case of adenocarcinoma was 7 mm. The frequency of malignancy among elevated mucosal lesions of gallbladder with a diameter of 13 to 16 mm, except in the case of adenomyomatosis was 42.1% (8/19 lesions). Of the 91 out of total 154 cases in which the elevated lesions were 10 mm or smaller in a diameter, malignant cases were observed in 5.5% (5/91 cases). Many of the malignant lesions had a solid pattern of internal echo and there was a significant difference in depiction rate on plain CT between benign and malignant lesions. We conclude that plan CT examination is helpful to differentiate benign from malignant lesions of the gallbladder. (author)

    Purpose: The aim of this retrospective study was to evaluate the diagnostic value of CT features of the gallbladder in the prediction of gallstone pancreatitis. Materials and methods: Eighty-six patients who underwent a diagnostic computed tomography (CT) scan for acute pancreatitis were included. The readers assessed the presence of pericholecystic increased attenuation of the liver parenchyma, enhancement of gallbladder (GB) and common bile duct (CBD) wall, pericholecystic fat strands, GB wall thickening, stone in the GB or CBD, and focal or diffuse manifestations of pancreatitis on abdominal CT scans. In addition, the maximal transverse luminal diameters of the GB and CBD were measured. Results: The presence of pericholecystic increased attenuation of the liver parenchyma, GB wall enhancement and thickening, pericholecystic fat strands, stone in the GB or CBD, and diffuse manifestations of pancreatitis achieved statistical significance for differentiation of gallstone induced pancreatitis from non-biliary pancreatitis (p < 0.05). The mean values of maximal transverse luminal diameter of GB and CBD were significantly higher in gallstone induced pancreatitis group (39.67 {+-} 7.26 mm, 10.20 {+-} 4.13 mm) than non-biliary pancreatitis group (27.01 {+-} 6.14 mm, 3.85 {+-} 2.51 mm, p < 0.0001). Conclusion: Gallbladder features of CT in patients with pancreatitis could be the valuable clues for the diagnosis of gallstone induced pancreatitis.

    The role of integrated (18)F-2-fluoro-2-deoxy-D-glucose positron emission tomography computed tomography (PET-CT) is uncertain in gallbladder cancer. The aim of this study was to show the role of PET-CT in gallbladder cancer patients. Fifty-three patients with gallbladder cancer underwent preoperative computed tomography (CT) and PET-CT scans. Their medical records were retrospectively reviewed. Twenty-six patients underwent resection. Based on the final outcomes, PET-CT was in good agreement (0.61 to 0.80) with resectability whereas CT was in acceptable agreement (0.41 to 0.60) with resectability. When the diagnostic accuracy of the predictions for resectability was calculated with the ROC curve, the accuracy of PET-CT was higher than that of CT in patients who underwent surgical resection (P=0.03), however, there was no difference with all patients (P=0.12). CT and PET-CT had a discrepancy in assessing curative resection in nine patients. These consisted of two false negative and four false positive CT results (11.3%) and three false negative PET-CT results (5.1%). PET-CT was in good agreement with the final outcomes compared to CT. As a complementary role of PEC-CT to CT, PET-CT tended to show better prediction about resectability than CT, especially due to unexpected distant metastasis.

    Full Text Available INTRODUCTION: There is no study relating magnetic resonance imaging (MRI to ultrasound (US findings in patients with Schistosomiasis mansoni. Our aim was to describe MRI findings inpatients with schistosomal liver disease identified by US. METHODS: Fifty-four patients (mean age 41.6±13.5years from an area endemic for Schistosomiasis mansoni were selected for this study.All had US indicating liver schistosomal fibrosis and were evaluated with MRI performed witha 1.5-T superconducting magnet unit (Sigma. RESULTS: Forty-seven (87% of the 54 patientsshowing signs of periportal fibrosis identified through US investigation had confirmed diagnosesby MRI. In the seven discordant cases (13%, MRI revealed fat tissue filling in the hilar periportalspace where US indicated isolated thickening around the main portal vein at its point of entryto the liver. We named this the fatty hilum sign. One of the 47 patients with MRI evidence ofperiportal fibrosis had had his gallbladder removed previously. Thirty-five (76.1% of the other46 patients had an expanded gallbladder fossa filled with fat tissue, whereas MRI of the remainingeleven showed pericholecystic signs of fibrosis. CONCLUSIONS: Echogenic thickening of thegallbladder wall and of the main portal vein wall heretofore attributed to fibrosis were frequentlyidentified as fat tissue in MRI. However, the gallbladder wall thickening shown in US (expandedgallbladder fossa in MRI is probably secondary to combined hepatic morphologic changes inschistosomiasis, representing severe liver involvement.

    Our purpose is to develop a standard method for preparing the bile for beta-glucuronidase determination by removal of bile acids and conjugated bilirubin which interfere with its activity. The bile acids and conjugated bilirubin in their purified solutions and in the diluted gallbladder biles could be extracted completely with cholestyramine in powder form or tetrahexylammonium chloride (THAC) in chloroform or ethyl acetate. The enzyme was, however, partially precipitated with cholestyramine and denatured by chloroform but not by ethyl acetate. A standard procedure, therefore, includes extraction of the diluted gallbladder bile with THAC in ethyl acetate, followed by determination of the maximal velocity (Vmax) of the enzyme by a kinetic method employing phenolphthalein glucuronide as the substrate. The average Vmax of beta-glucuronidase in the 20 normal gallbladder biles was 165 +/- 86 nmol/min/ml (mean +/- SD), a 23.5-fold increase over the activity before extraction. The measured activity represented the true activity of the enzyme in the bile for recovery of activity of the enzyme added to the bile was practically complete.

    The change from laparotomy to laparoscopy for cholecystectomy has raised the question of how to manage concomitant bile duct stones. The present-day interest--and controversy--has focused on a transcystic approach reported to be feasible in 66-96% of cases, but without explaining the necessary prerequisite: the widening of the cystic duct. The cystic duct, wide mainly in patients with bile duct stones, has been reported to be highly variable: from strictured to very wide. The present study aims at comparing the trypsin level in the gallbladder bile and the cystic duct morphology and width in patients with and without bile duct stones. A prospective series of 63 gallstone patients, 30 with and 33 without bile duct stones (controls), underwent cholecystectomy and bile duct clearance. The study includes the trypsin level in the gallbladder bile, the width and morphology of the cystic duct, and the size of the gallstones. The patients with bile duct stones had, in contrast to the controls, higher trypsin levels in the gallbladder bile (P extraction feasible.

    An unsolved problem of laparoscopic cholecystectomy is the optimal method of removing the gallbladder with thick walls and a large stone burden. Proposed solutions include fascial dilatation, stone crushing, and ultrasonic, high-speed rotary, or laser lithotripsy. Our observation was that extension of the fascial incision to remove the impacted gallbladder was time efficient and did not increase postoperative pain. We reviewed the narcotic requirements of 107 consecutive patients undergoing laparoscopic cholecystectomy. Fifty-two patients required extension of the umbilical incision, and 55 patients did not have their fascial incision enlarged. Parenteral meperidine use was 39.5 +/- 63.6 mg in the patients requiring fascial incision extension and 66.3 +/- 79.2 mg in those not requiring fascial incision extension (mean +/- standard deviation). Oral narcotic requirements were 1.1 +/- 1.5 doses vs 1.3 +/- 1.7 doses in patients with and without incision extension, respectively. The wide range of narcotic use in both groups makes these apparent differences not statistically significant. We conclude that protracted attempts at stone crushing or expensive stone fragmentation devices are unnecessary for the extraction of a difficult gallbladder during laparoscopic cholecystectomy.

    Recent enthusiasm in the surgical community for less invasive surgical approaches has resulted in widespread application of single-incision techniques. This has been most commonly applied in laparoscopic cholecystectomy in general surgery. Cosmesis appears to be improved, but other advantages remain to be seen. Feasibility has been demonstrated, but there is little description in the current literature regarding complications. We report the case of a patient who previously underwent single-incision laparoscopic cholecystectomy for symptomatic gallstone disease. After a brief symptom-free interval, she developed acute pancreatitis. At evaluation, imaging results of ultrasonography and magnetic resonance cholangiopancreatography demonstrated a retained gallbladder with cholelithiasis. The patient was subsequently referred to our hospital, where she underwent further evaluation and surgical intervention. Our patient underwent 4-port laparoscopic remnant cholecystectomy with transcystic common bile duct exploration. Operative exploration demonstrated a large remnant gallbladder and a partially obstructed cystic duct with many stones. Transcystic exploration with balloon extraction resulted in duct clearance. The procedure took 75 minutes, with minimal blood loss. The patient's postoperative course was uneventful. Final pathology results demonstrated a remnant gallbladder with cholelithiasis and cholecystitis. This report is the first in the literature to describe successful laparoscopic remnant cholecystectomy and transcystic common bile duct exploration after previous single-port cholecystectomy. Although inadvertent partial cholecystectomy is not unique to this technique, single-port laparoscopic procedures may result in different and significant complications.

    The left sided gallbladder, being a rare occurrence, may create diagnostic problem especially when it becomes infected. Recently, we have experienced 2 cases of infection of left sided gallbladder at the Department of Radiology, St Mary's Hospital, Catholic Medical College. Case I was a 32-year-old housewife with dyspepsia, epigastric pain and recurring bouts of high fever of 2 months duration. Under the provisional diagnosis of liver abscess liver scan was performed which revealed well defined cold area in the left lobe supporting the provisional diagnosis. Tender cystic mass was aspirated and pus was drained. The injected air at the occasion of aspiration outlined well defined cystic structure. Because aspiration failed to control the symptoms, laparotomy was performed. Surgeon found a left sided gallbladder which was empyematous. Case II was a 38 year old business man admitted to the hospital because of tender ill defined mass in mid epigastrium. The patient was febrile (39.4 .deg. C) and anemic. An upper GI series disclosed an irregular filling defect involving the antrum of the stomach. The mass was primarily extrinsic but was closely fixed to the gastric wall. Surgical intervention revealed chronic cholecystitis and pericholecystitis with thick adhesion to the distal stomach.

    Gallbladder cancer (GBC) is an aggressive neoplasia associated with late diagnosis, unsatisfactory treatment, and poor prognosis. Molecular mechanisms involved in GBC pathogenesis remain poorly understood. Connective tissue growth factor (CTGF) is thought to play a role in the pathologic processes and is overexpressed in several human cancers, including GBC. No information is available about CTGF expression in early stages of gallbladder carcinogenesis. Objective.- To evaluate the expression level of CTGF in benign and malignant lesions of gallbladder and its correlation with clinicopathologic features and GBC prognosis. Connective tissue growth factor protein was examined by immunohistochemistry on tissue microarrays containing tissue samples of chronic cholecystitis (n = 51), dysplasia (n = 15), and GBC (n = 169). The samples were scored according to intensity of staining as low/absent and high CTGF expressers. Statistical analysis was performed using the χ(2) test or Fisher exact probability test with a significance level of P Connective tissue growth factor expression showed a progressive increase from chronic cholecystitis to dysplasia and then to early and advanced carcinoma. Immunohistochemical expression (score ≥2) was significantly higher in advanced tumors, in comparison with chronic cholecystitis (P < .001) and dysplasia (P = .03). High levels of CTGF expression correlated with better survival (P = .04). Our results suggest a role for CTGF in GBC progression and a positive association with better prognosis. In addition, they underscore the importance of considering the involvement of inflammation on GBC development.

    The characteristics of meal-induced gallbladder emptying in healthy individuals are subject to wide variation. We hypothesized that some of the observed variation might relate to ingestion of the meal during different phases of the migrating motor complex (MMC). Recording of gastrointestinal...... pressure was combined with scintigraphic recording of bile kinetics during infusion of 99mTc-HIDA. The material consisted of 12 healthy men. Group 1 (n = 6) had a fat-rich meal in phase I, and group 2 (n = 6) had the meal in a phase II. With the end of the meal ingestion as zero, the following results...... emerged. The subjects in group 1 had a median (range) lag period before beginning of gallbladder emptying of 13.5 (9.0-22.5) min. In group 2 gallbladder emptying began during the meal ingestion in four subjects, and the median lag period was 0 min (minimum, -9.0; maximum, 13.5 (p = 0.02)). The median...

    Bariatric surgery is the most effective therapy for weight loss in patients with morbid obesity. One of the most common long-term complications includes cholelithiasis. There is not a clear consensus in how to treat an asymptomatic gallbladder disease before and after bariatric surgery. Prospective study with every patient submitted to bariatric surgery from 2012 to 2014. The gallbladder status was assessed with an ultrasound before and after surgery (12 months), and a conservative management was conducted for patients with asymptomatic disease (preoperative and de novo); the need for delayed cholecystectomy was reported. Secondarily, an analysis of weight loss (%EWL) and gallbladder status was performed. Two-hundred and two bariatric surgeries were performed. The global incidence of preoperative gallbladder disease was 34.3 %, with 14.2 % presenting sludge, 20.1 % asymptomatic gallstones, and 2.3 % symptomatic gallstones. The final analysis was based on 146 patients; female sex comprised 81.1 % of cases with a mean age of 38.5 years. After 12 months, de novo gallbladder disease was observed in 21.2 %. The overall rate of cholecystectomy because of symptomatic disease after 12 months was 3.4 % (2 % developed acute cholecystitis). There were no differences in %EWL between patients with de novo gallbladder disease and those without. Conservative management of asymptomatic gallbladder disease in candidates to bariatric surgery is safe and can be offered in every case, based on the low percentage of patients requiring further cholecystectomy after 12 months. Also, a conservative management can be offered to patients developing de novo sludge/cholelithiasis without related symptoms.

    Extraction of a gallbladder through an endoscopic overtube during natural orifice translumenal endoscopic surgery (NOTES) transgastric cholecystectomy avoids potential injury to the esophagus. This study examined the rate of successful gallbladder specimen extraction through an overtube and hypothesized that preoperative ultrasound findings could predict successful specimen passage. Gallbladder specimens from patients undergoing laparoscopic cholecystectomy were measured, and an attempt was made to pull the specimens through a commercially available overtube with an inner diameter of 16.7-mm. A radiologist blinded to the outcomes reviewed the available preoperative ultrasound measurements from these patients. Ultrasound dimensions including gallbladder length, width, and depth; wall thickness; common bile duct diameter; and size of the largest gallstone (LGS) were recorded. Multiple logistic regression analysis was performed to determine whether ultrasound findings and patient characteristics (age, body mass index [BMI], and sex) could predict the ability of a specimen to pass through the overtube. Of 57 patients, 44 (77%) who had preoperative ultrasounds available for electronic review were included in the final analysis. Gallstones were present in 35 (79%) of these 44 patients. Intraoperative gallbladder perforation occurred in 18 (41%) of the 44 patients, and 16 (36%) of the 44 gallbladders could be extracted through the overtube. Measurement of LGS was possible for 23 patients, and indeterminate gallstone size (IGS) was determined for 12 patients. The rate for passage of perforated versus intact gallbladders was similar (40% vs. 23%; p = 0.054). The LGS (odds ratio [OR], 1.17; 95% confidence interval [CI], 1.02-1.33; p = 0.021) and IGS (OR, 22.97; 95% CI, 1.99-265.63; p = 0.025) predicted failed passage on multivariate logistic regression analysis. The passage rate was 80% for LGS smaller than 10 mm or no stones present, 18% for LGS 10 mm or larger, and 8% for

    Gallbladder carcinoma is the most common and aggressive malignancy of the biliary tree and highly expresses CD147, which is closely related to disease prognosis in a variety of human cancers. Doxycycline exhibited anti-tumor properties in many cancer cells. CD147 antagonist peptide-9 is a polypeptide and can specifically bind to CD147. The effect of these two drugs on gallbladder cancer cells has not been studied. The aim of this study is to investigate the effect of doxycycline and antagonist peptide-9 on gallbladder carcinoma cells and the possible mechanism of inhibition on cancer cell of doxycycline. To investigate the effects of doxycycline and antagonist peptide-9 on gallbladder carcinoma cells (GBC-SD and SGC-996), cell proliferation, CD147 expression, and early-stage apoptosis rate were measured after treated with doxycycline. Matrix metalloproteinase-2 and matrix metalloproteinase-9 activities were measured after treated with different concentrations of doxycycline, antagonist peptide-9, and their combination. The results demonstrated that doxycycline inhibited cell proliferation, reduced CD147 expression level, and induced an early-stage apoptosis response in GBC-SD and SGC-996 cells. The matrix metalloproteinase-2 and matrix metalloproteinase-9 activities were inhibited by antagonist peptide-9 and doxycycline, and the inhibitory effects were enhanced by combined drugs in gallbladder carcinoma cell lines. Taken together, doxycycline showed inhibitory effects on gallbladder carcinoma cell lines and reduced the expression of CD147, and this may be the mechanism by which doxycycline inhibits cancer cells. This study provides new information and tries to implement the design of adjuvant therapy method for gallbladder carcinoma.

    Ascaris lumbricoides is one of the most common intestinal infections in developing countries, including Kosovo. In contrast to migration to the bile duct, migration of the worm to the gallbladder, due to the narrow and tortuous nature of the cystic duct, is rare. When it does occur, it incites acalculous cholecystitis. This case series describes a 16-month-old Albanian girl, a 22-month-old Albanian girl, a 4-year-old Albanian girl, and a 10-year-old Albanian boy. Here we report our experience with gallbladder ascariasis including clinical manifestations, diagnostic procedures, and treatment. Fever, diarrhea and vomiting, dehydration, pale appearance, and weakness were the manifestations of the primary disease. In all patients, a physical examination revealed reduced turgor and elasticity of the skin. Abdomen was at the level of the chest, soft, with minimal palpatory pain. The liver and spleen were not palpable. A laboratory examination was not specific except for eosinophilia. There were no pathogenic bacteria in coproculture but Ascaris was found in all patients. At an ultrasound examination in all cases we found single, long, linear echogenic structure without acoustic shadowing containing a central, longitudinal anechoic tube with characteristic movement within the gallbladder. Edema of the gallbladder wall was suggestive of associated inflammation. There were no other findings on adjacent structures and organs. All patients received mebendazole 100 mg twice a day for 3 days. They also received symptomatic therapy for gastroenteritis. Because of elevated markers of inflammation all patients were treated with antibiotics, assuming acute cholecystitis, although ultrasound was able to confirm cholecystitis in only two of our four patients. Since the length of stay was dependent on the primary pathology it was 7 to 10 days. At control ultrasounds on 14th day, third and sixth month, all patients were free of ascariasis. Gallbladder ascariasis should be considered in

    Accidental rupture of the gallbladder is an event which occurs in up to 20% of laparoscopic cholecystectomies, mainly in those where dissection is difficult, or during extraction when the gallbladder is withdrawn directly through the laparoscope port. It has been commonly assumed that contamination by bile in the abdominal cavity could be a cause of infection and lead to the formation of a residual abscess or even to surgical wound infection. It is common practice, therefore, for the surgeon to prescribe the application of an antibiotic at the moment when gallbladder perforation occurs. To compare 2 groups of similar patients, to determine whether administration of antibiotics, started during surgery, is actually useful in reducing the risk of residual abscess or infection in the surgical wound. The study considered a total of 166 patients who had suffered accidental perforation of the gallbladder during elective laparoscopic cholecystectomy. This total was divided at random into 2 groups: group A (80 patients) who received a dose of 1 g of Cefotaxime at the moment of gallbladder rupture, followed by 2 more doses at intervals of 8 hours in the immediate postoperative period; and group B (86 patients) who did not receive any antibiotic treatment at all. The dependent variables observed were surgical wound infection and residual abscess: and the control variables were age, sex, length of operation time, intercurrent illnesses, and American Society of Anesthesiologists (ASA) classification. Two patients (2.5%) in group A developed a surgical wound infection, against 3 cases (3.4%) in group B, the result having no statistical significance. No patients developed residual abscess. In a multivariant analysis, the following were identified as independent factors significantly associated with the onset of surgical wound infection (Pgallbladder during laparoscopic cholecystectomy is not necessary.

    Chile’s gallbladder cancer rates are among the highest in the world, being the first cancer killer among Chilean women. To provide insights into the etiology of gallbladder cancer, we conducted an ecologic study examining the geographical variation of gallbladder cancer and several putative risk factors. The relative risk of dying from gallbladder cancer (relative to the national average mortality rate) between 1985 and 2003 was estimated for each of the 333 Chilean counties, using a hierarchical Poisson regression model, adjusting for age, sex, and geographical location. The risk of gallbladder cancer mortality was analyzed in relation to region (costal, inland, northern, and southern), poverty, Amerindian (Mapuche) population, typhoid fever, and access to cholecystectomy, using logistic regression analysis. There were 27,183 gallbladder cancer deaths, age-sex-adjusted county mortality rates ranging from 8.2 to 12.4 per 100,000 inhabitants, being higher in inland and southern regions; compare to the north-coastal, the northern-inland region had a 10-fold risk odds ratio (OR) (95% of confidence interval (95% CI): 2.4–42.2) and the southern-inland region had a 26-fold risk (OR 95%CI: 6.0–114.2). Independent risk factors for gallbladder cancer were: ethnicity (Mapuche) OR:3.9 (95%CI 1.8–8.7), typhoid fever OR:2.9 (95%CI 1.2–6.9), poverty OR:5.1 (95%CI 1.6–15.9), low access to cholecystectomy OR:3.9 (95%CI 1.5–10.1), low access to hospital care OR:14.2 (95%CI 4.2–48.7) and high urbanization OR:8.0 (95%CI 3.4–18.7). Our results suggest that gallbladder cancer in Chile may be related to both genetic factors and poor living conditions. Future analytic studies are needed to further clarify the role of these factors in gallbladder cancer etiology. PMID:18566990

    To examine the associations between socioeconomic/occupational factors and liver cancer at various anatomic sites (including primary liver, gallbladder and other cancers). We carried out a follow-up study on the economically active Swedish population, based on the Swedish Family-Cancer Database. Standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) were calculated in different social classes and occupations. For primary liver cancer, farmers were at a decreased risk; increased risks were observed for male sales agents, journalists, seamen, waiters, cooks and female beverage manufacture workers. Similar patterns were observed for gallbladder cancer; workers employed as journalists, sales agents, cooks and stewards, and public safety workers showed increased risk. Only male transport workers showed increased risk of cancers in other parts. Occupations with high consumption of alcohol and/or high prevalence of smoking associated with a risk of liver and gallbladder cancers. The present study suggests that the effects of socioeconomic factors on liver cancer of different subsites are similar; alcohol drinking is a risk factor of gallbladder cancer because of the covariation of primary liver and gallbladder cancers in occupational groups.

    Preoperative jaundice is frequent in gallbladder cancer (GBC) and indicates advanced disease. Resection is rarely recommended to treat advanced GBC. An aggressive surgical approach for advanced GBC remains lacking because of the association of this disease with serious postoperative complications and poor prognosis. This study aims to re-assess the prognostic value of jaundice for the morbidity, mortality, and survival of GBC patients who underwent surgical resection with curative intent. GBC patients who underwent surgical resection with curative intent at a single institution between January 2003 and December 2012 were identified from a prospectively maintained database. A total of 192 patients underwent surgical resection with curative intent, of whom 47 had preoperative jaundice and 145 had none. Compared with the non-jaundiced patients, the jaundiced patients had significantly longer operative time (p jaundice was the only independent predictor of postoperative complications. The jaundiced patients had lower survival rates than the non-jaundiced patients (p jaundiced patients. The survival rates of the jaundiced patients with preoperative biliary drainage (PBD) were similar to those of the jaundiced patients without PBD (p = 0.968). No significant differences in the rate of postoperative intra-abdominal abscesses were found between the jaundiced patients with and without PBD (n = 4, 21.1% vs. n = 5, 17.9%, p = 0.787). Preoperative jaundice indicates poor prognosis and high postoperative morbidity but is not a surgical contraindication. Gallbladder neck tumors significantly increase the surgical difficulty and reduce the opportunities for radical resection. Gallbladder neck tumors can independently predict poor outcome. PBD correlates with neither a low rate of postoperative intra-abdominal abscesses nor a high survival rate.

    Particle Induced X-Ray Emission is a suitable method for the analysis of biological samples in which heavy trace elements are contained in light matrix elements. It is very important to know which factors or probably elements act as initial seed and lead to growing the sands. The goal of this study was to compare the relative values of Fe/K, Cu/K and Zn/K for gallstones, gallbladder, and bile of a specific patient for studying the origination of forming the gallstones. Materials and Methods Human gallbladder, bile, and gallstone samples were obtained by surgical operation from 15 patients and are bombarded by 2.0 MeV energy proton beams produced by van de Graaff accelerator in vacuum. All .. the gallstones were chosen of pigment type of stones and, all the patients were adults. In contrast with conventional methods, the shell and center of the sands has been analyzed separately. The PIXE spectrum analysis was performed using the nonlinear least square fitting code AXIL and GUPIX. Results: The results of detected minor and trace elements shows that the precipitation of calcium salt in the bile lead to reduction of crystals' formation. Elemental comparison of pigment type of gallstone and bile shows that the concentration of calcium in the shell of the stones is four times more than that in the bile. Conclusion: Precipitation of the calcium from the saturated bile on the cholesterols as a seed of gallstones led to reduced sands formation. Analysis of the gallbladder of the same patients revealed no relation between elemental concentrations of bile and gallstones

    III Rome Criteria of functional gastrointestinal disorders in children, distinguished the disturbances with abdominal pain, to which irritable bowel syndrome, functional abdominal pains, functional dyspepsia and abdominal migraine were included. THE AIM OF THE STUDY was sonographic assessment of the gallbladder and its contractility in functional abdominal pain and irritable bowel syndrome in children. The study comprised 96 children aged 6 to 18 years, 59 girls and 37 boys. Depending on diagnosis, the children were divided into three groups. 38 children with functional abdominal pain constituted the first group, 26 children with irritable bowel syndrome were included to the second group, the third group consisted of 32 healthy children (control group). Diagnosis of functional abdominal pain and irritable bowel syndrome was made based on the III Rome Criteria. In irritable bowel syndrome both forms with diarrhea (13) and with constipation (13) were observed. Anatomy and contractility of the gallbladder were assessed by ultrasound examination. The presence of septum, wall thickness, thick bile, vesicle volume in fasting state and 30th and 60th minute after test meal were taken into consideration. Test meal comprised about 15% of caloric requirement of moderate metabolism. Children with bile stones and organic diseases were excluded from the study. Thickened vesicle wall and thick bile were present more frequently in children with irritable bowel syndrome and functional abdominal pain than in control group (p functional abdominal pain than in irritable bowel syndrome and control group (p = 0.003, p = 0.05). Vesicle contractility after test meal was greatest in children with functional abdominal pain. Evaluation of diminished (smaller than 30%) and enlarged (greater then 80%) gallbladder contractility at 30th and 60th minute after test meal demonstrated disturbances of contractility in children with irritable bowel syndrome and functional abdominal pain.

    Cancer of the gallbladder is radioresistant. When it was found inoperable, she was subjected to radiotherapy combined with aclarubicin and neocarzinostatin. Therapeutic effectiveness was confirmed at autopsy as she later succumbed to uterine cervical cancer. Thus, the present radiochemotherapeutic regimen would probably provide a means of overcoming those radioresistant inoperable malignancies. Intravenous administrations of appropriate antibiotics such as azthreonam and reniran may probably be helpful in the prevention and treatment of septic peritonitis possible during the course of reinforced radiotherapy of the abdomen.

Computed tomogram scan of the abdomen and abdominal ultrasound showed normal gallbladder and common bile duct (CBD). Subsequently magnetic resonance cholangiopancreaticogram showed choledocholithiasis. Endoscopic retrograde cholangiopancreaticogramwith sphincterotomy and CBD stone extraction was performed. The patient progressively improved with antibiotic therapy Choledocholithiasis should be considered as a source of clostridium perfringens bacteremia especially in the setting of elevated liver enzymes with cholestatic pattern.

    Gene therapy has become an important strategy for treatment of malignancies, but problems remains concerning the low gene transferring efficiency, poor transgene expression and limited targeting specific tumors, which have greatly hampered the clinical application of tumor gene therapy. Gallbladder cancer is characterized by rapid progress, poor prognosis, and aberrantly high expression of Survivin. In the present study, we used a human tumor-specific Survivin promoter-regulated oncolytic adenovirus vector carrying P53 gene, whose anti-cancer effect has been widely confirmed, to construct a wide spectrum, specific, safe, effective gene-viral therapy system, AdSurp-P53. Examining expression of enhanced green fluorecent protein (EGFP), E1A and the target gene P53 in the oncolytic adenovirus system validated that Survivin promoter-regulated oncolytic adenovirus had high proliferation activity and high P53 expression in Survivin-positive gallbladder cancer cells. Our in vitro cytotoxicity experiment demonstrated that AdSurp-P53 possessed a stronger cytotoxic effect against gallbladder cancer cells and hepatic cancer cells. The survival rate of EH-GB1 cells was lower than 40% after infection of AdSurp-P53 at multiplicity of infection (MOI) = 1 pfu/cell, while the rate was higher than 90% after infection of Ad-P53 at the same MOI, demonstrating that AdSurp-P53 has a potent cytotoxicity against EH-GB1 cells. The tumor growth was greatly inhibited in nude mice bearing EH-GB1 xenografts when the total dose of AdSurp-P53 was 1 × 10(9) pfu, and terminal dUTP nick end-labeling (TUNEL) revealed that the apoptotic rate of cancer cells was (33.4 ± 8.4)%. This oncolytic adenovirus system overcomes the long-standing shortcomings of gene therapy: poor transgene expression and targeting of only specific tumors, with its therapeutic effect better than the traditional Ad-P53 therapy regimen already on market; our system might be used for patients with advanced gallbladder cancer and

    Full Text Available This case describes an intraoperative incidental finding and surgical removal of ectopic liver tissue attached to the gallbladder during a standard laparoscopic cholecystectomy for acute cholecystitis. These anomalies are rare, with interesting associations and possible clinically relevant complications. The details of the case, along with a brief literature review of embryology, common ectopic sites, and associations/complications, are presented in this paper. Since laparoscopic cholecystectomy is a very common procedure, it is important to increase vigilance of ectopic liver tissues during surgeries to minimize complications and provide optimal management.

    Full Text Available The taeniasis-cysticercosis complex is a long known zoonotic parasitosis characteristic of underdeveloped countries. In addition to its public health significance, this parasitosis is cause of economic losses to the beef production chain, and synonymous of technical inadequacy in relation to the adoption of Good Agricultural Practices. The occurrences of both human teniasis and bovine cysticercosis could and should be controlled with basic sanitary measures. However, there is much variation in the occurrence of the disease in cattle, characterizing a low rate of technical development as well as problems related to the adoption of basic sanitation measures. This review describes, in details, the causative agent and its epidemiological chain, besides raising current information about the occurrence of bovine cysticercosis in different regions of Brazil, aiming at the adoption of prophylactic measures by different segments responsible.

    The major objectives of this project were to establish the pattern of basal hepatic bile flow and the effects of intravenous administration of cholecystokinin on the liver, sphincter of Oddi, and gallbladder, and to identify reliable parameters for the diagnosis of sphincter of Oddi spasm (SOS). Eight women with clinically suspected sphincter of Oddi spasm (SOS group), ten control subjects (control group), and ten patients who had recently received an opioid (opioid group) were selected for quantitative cholescintigraphy with cholecystokinin. Each patient was studied with 111-185 MBq (3-5 mCi) technetium-99m mebrofenin after 6-8 h of fasting. Hepatic phase images were obtained for 60 min, followed by gallbladder phase images for 30 min. During the gallbladder phase, 10 ng/kg octapeptide of cholecystokinin (CCK-8) was infused over 3 min through an infusion pump. Hepatic extraction fraction, excretion half-time, basal hepatic bile flow into the gallbladder, gallbladder ejection fraction, and post-CCK-8 paradoxical filling (>30% of basal counts) were identified. Seven of the patients with SOS were treated with antispasmodics (calcium channel blockers), and one underwent endoscopic sphincterotomy. Mean (+/-SD) hepatic bile entry into the gallbladder (versus GI tract) was widely variable: it was lower in SOS patients (32%+/-31%) than in controls (61%+/-36%) and the opioid group (61%+/-25%), but the difference was not statistically significant. Hepatic extraction fraction, excretion half-time, and pattern of bile flow through both intrahepatic and extrahepatic ducts were normal in all three groups. Gallbladder mean ejection fraction was 9%+/-4% in the opioid group; this was significantly lower (Pgallbladder refluxed into intrahepatic ducts; it reentered the gallbladder after cessation of CCK-8 infusion (paradoxical gallbladder filling) in all eight patients with SOS, but in none of the patients in the other two groups.

    Full Text Available A 65-year-old man with chronic hepatitis C and no history of alcohol abuse was admitted to our liver unit for the recent development of massive ascites and presumed hepatorenal syndrome. In the preceding two weeks, he had received medical treatment for acute pancreatitis and cholecystitis. Abdominal paracentesis demonstrated a cloudy, orange peritoneal fluid, with total protein concentration 3.6 g/dl, serum-ascites albumin gradient 1.0 g/dl, and ratios of ascites-serum bilirubin and amylase approximately 8:1. Diagnostic imaging demonstrated no pancreatic pseudocysts. Ten days later, at laparotomy, acalculous perforation of the gallbladder was identified. After cholecystectomy, amylase concentration in the ascitic fluid dropped within a few days to 40% of serum values; ascites disappeared within a few weeks. We conclude that in the presence of a perforated gallbladder, pancreatobiliary reflux was responsible for this unusual combination of choleperitoneum and pancreatic ascites, which we propose to call pancreatobiliary ascites.

    Gallbladder carcinoma (GBC) is a commonly-seen malignancy of the biliary tract characterized by difficult early diagnosis, rapid growth, early metastasis, and poor prognosis. Nearly half of GBC patients also have jaundice, which is a mark of the advanced stage of GBC. The role of radical resection in patients of gallbladder carcinoma with jaundice is still a matter of uncertainty, which we attempted to clarify in this study. Totally, 251 GBC patients who received treatment at the Eastern Hepatobiliary Surgery Hospital (EHBH) from December 2002 to January 2010 were recruited into this study. We divided them into group A (jaundice group, n=117) and group B (non-jaundice group, n=134). Clinical records and follow-up data were collected and retrospectively analyzed in both groups. Compared with group A, patients in group B had a longer median survival time ((6.0±0.5) months vs. (15.0±2.6) months, Pjaundice (n=111), was still longer than that in patients with jaundice (n=116) (Pjaundice patients and non-jaundice patients; (12.0±4.3) months vs. (18.0±3.0) months (P>0.05). GBC with jaundice usually implies advanced stage disease and a poor prognosis for the patients. However, our findings indicate that as long as the patient's condition allows, radical resection is still feasible for GBC patients with jaundice, and may achieve a prognosis close to those GBC patients without jaundice.

    Laparoscopic common bile duct exploration (LCBDE) for stone can be carried out by either laparoscopic transcystic stone extraction (LTSE) or laparoscopic choledochotomy (LC). It remains unknown as to which approach is optimal for management of gallbladder stone with common bile duct stones (CBDS) in Chinese patients. From May 2000 to February 2009, we prospective treated 346 consecutive patients with gallbladder stones and CBDS with laparoscopic cholecystectomy and LCBDE. Intraoperative findings, postoperative complications, postoperative hospital stay and costs were analyzed. Because of LCBDE failure,16 cases (4.6%) required open surgery. Of 330 successful LCBDE-treated patients, 237 underwent LTSE and 93 required LC. No mortality occurred in either group. The bile duct stone clearance rate was similar in both groups. Patients in the LTSE group were significantly younger and had fewer complications with smaller, fewer stones, shorter operative time and postoperative hospital stays, and lower costs, compared to those in the LC group. Compared with patients with T-tube insertion, patients in the LC group with primary closure had shorter operative time, shorter postoperative hospital stay, and lower costs. In cases requiring LCBDE, LTSE should be the first choice, whereas LC may be restricted to large, multiple stones. LC with primary closure without external drainage of the CBDS is as effective and safe as the T-tube insertion approach.

    During laparoscopic cholecystectomy, a large stone burden may cause difficulty when extracting the gallbladder through the abdominal wall. Currently, the alternatives available to the surgeon include increasing the incision, removing stones singly, or utilizing complex fragmentation techniques like the pulsed dye laser. We have employed an electromechanical rotary gallstone lithotrite (RGL) to fragment stones to an aspiratable size. Initially, cholesterol spheres were pulverized in a latex balloon to demonstrate the efficacy of the device. Then, human gallstones were placed in the balloon and reduced to fragments less than or equal to 1 mm from initial sizes of 4-24 mm. Human stones were then inserted in ex vivo porcine gallbladders in a controlled experiment and treated with the device. Ten out of 12 tests were completed within 30 s; one test required 49 s and one 105 s to achieve complete fragmentation. Blinded histological evaluation demonstrated that tissue abrasion caused by use of the device would not interfere with the diagnosis of unsuspected malignancy. Clinical trials have now commenced under the auspices of the hospital ethical committee.

    To present the results of the biliary endoscopic approach (ERCP) followed by laparoscopic cholecystectomy (LC) in the management of biliary lithiasis (gallbladder and common bile duct--CBD). From 1997 to March 2003 37 patients with biliary lithiasis were treated by endoscopic sphincterotomy (ES) with stone extraction, followed after 24-48 hours by LC. The indications for ERCP were presence of an obstructive jaundice (n=32) and a dilated CBD at the ultrasound examination (n=5). Selective biliary cannulation was obtained in 35 (94.6%) cases, in all of them with successful papillotomy. Stones were found in all patients. CBD clearances for calculi (from 1 to 8) was obtained in 33 of 35 patients (94.3%), the rest of 2 being managed by open laparotomy. Antibiotics were administrated in all patients. Laparoscopic cholecystectomy was performed after 24-48 hours, with one conversion (3%). Postoperative morbidity was 12.1%: 2 transitory pancreatic reactions and 2 wound infections. Endo-Lap method is a useful management alternative for combined gallbladder and CBD lithiasis. It has all the advantages of the two mini-invasive procedures (fast recovery, short hospitalization, low costs) and a less postoperative morbidity in patients with high risk.

    Gallbladder cancer (GBC) is an aggressive malignancy of the bile duct, which is associated with a low (5-year) survival and poor prognosis. The transcription factor HIF-1α is implicated in the angiogenesis, cell survival, epithelial mesenchymal transition (EMT) and invasiveness of GBC. In this study, we have investigated the role of HIF-1α in the pathobilogy of GBC and effect of hispidulin on the molecular events controlled by this transcription factor. We observed that hispidulin caused induction of apoptosis, blockade of growth and cell cycle progression in GBC cells. Our results have demonstrated for the first time that hispidulin-exerted anti-tumor effect involved the suppression of HIF-1α signaling. Hispidulin was found to repress the expression of HIF-1α protein dose-dependently without affecting the HIF-1α mRNA expression. In addition, the inhibition of HIF-1α protein synthesis was revealed to be mediated through the activation of AMPK signaling. Hispidulin also sensitized the tumor cells to Gemcitabine and 5-Fluoroucil by down-regulating HIF-1α/P-gp signaling. Given the low cost and exceedingly safe profile, hispidulin appears to be a promising and novel chemosensitizer for GBC treatment. - Highlights: • Hispidulin inhibits proliferation of gallbladder cancer cells by targeting HIF-1α. • Hispidulin regulates HIF-1α via activating AMPK signaling. • Hispidulin sensitized the GBC cells to chemotherapeutics by down-regulating P-gp.

    To clarify the relationship between the pattern of cholecystolithiasis and the gross features of segmental adenomyomatosis of the gallbladder. Fifty-five consecutive patients with segmental adenomyomatosis with calcified gallbladder stones defined on CT were retrospectively analyzed in terms of (i) stone location (fundal vs. neck compartment) and (ii) size of the largest stone as a function of the extent of segmental mural thickening (type A, limited at the narrow segment; type B, partially extended in the fundal direction; type C, involving the entire fundal compartment). The extent of segmental mural thickening in patients with cholecystolithiasis was compared with a control group (n = 48) lacking stones. Stones were found more frequently in the fundal compartment in 48 patients compared to the neck compartment in 12 patients (p<0.001). The mean size of the largest stone in type C (5.4 ± 4.9 mm) was larger than in type A (2.3 ± 2.2 mm) (p=0.033). In patients with cholecystolithiasis, type C segmental thickening was predominant (69%) compared to the control group (42%) (p=0.012). In addition to a higher prevalence of stones, a wide extent of mural thickening combined with large stone size in the fundal compartment suggests the contribution of segmental adenomyomatosis to stone formation and chronic inflammation.

    We performed this study to evaluate the changes of gallbladder ejection fraction (GBEF) in diabetic patients with or without autonomic neuropathy. This study included 37 diabetic patients (25 women, 12 men, mean age 51 years) and 24 normal controls (10 women, 14 men, mean age 38 years). After intravenous injection of 185 MBq of 99m T c -DISIDA, serial anterior abdominal images were acquired before and after fatty meal. Regions of interest were applied on gallbladder and right hepatic lobe on 60 and 90 minute images to calculate GBEF. GBEF was significantly reduced in diabetes with autonomic neuropathy (43±12.3%) and without autonomic neuropathy (57.5±13.2%) compared with normal controls (68±11.6%, p 0.05). When 50.2% of GBEF was used as the criteria for diabetic autonomic neuropathy, the sensitivity and specificity were 80%, 76.5%, respectively. The area under receiver operating characteristic curve was 0.846. GBEF of diabetic patients with autonomic neuropathy was significantly reduced than that of diabetic patients without autonomic neuropathy.=20

    In order to evaluate microstructural changes after shock wave exposure, gross, light microscopic and transmission electron microscopic findings were analyzed with rabbit gallbladders. A preliminary study(2 rabbits) was performed to determine the dosage intensity of shock waves needed to inflict damage, using a EDAP LT 01 piezoelectric extracorporeal shock wave lothotriptor. The Gallbladders of three different groups of rabbits were given shock waves of various intensity. A storage value of 100, 50, 25 at rate of 20/sec under 80% power were given to group I (4 rabbits), group II (4 rabbits), and group III (3 rabbits), respectively. The rabbits were sacrificed 6-12 hours later. The observed pathologic changes in the transmission electron microscopy were vaculization of cytoplasm and swelling of epithelial cells with dilatation and structural alteration of intracellular organelles, especially endoplasmic reticulum. Cell membrane rupture and necrosis were observed at the markedly affected area. The structural changes of intracellular organelles were minimally found at a storage value of 25. However, above pathologic changes with dilatation and structural alterations of endoplasmic reticulums were more profound at value of 100. Early histologic changes induced by shocked waves are dose dependent and findings of cellular damage caused by ESWL might be explained as above.

    This study focuses on the elemental distribution in different types of gallstones; bile and gallbladder tissues using neutron activation analysis technique based on k0-INAA method in Tajura center. Samples were collected from patients who undergone open surgery of gallbladder (cholecystectomy) at El-khadra University Hospital in Tripoli, aged between 23-80 yr. The samples obtained from patients who don't suffer from any chronic diseases, therefore, they were not taking any medications that might elevate the concentration of certain elements in the body. Samples were prepared and lyophilized by different process in a clean room. All samples were irradiated in the reactor and measured in the neutron activation laboratory. In order to obtain accurate results, Au and Zr flux monitors were irradiated with the samples for flux ratio (f) and α determinations and to account for any flux variations within the container. The irradiations of the samples were carried out in the reactor channels VCR11 and VCR12 for 8 hours under f (32 and 14) and α parameters (0.0183, 0.1678) respectively. More than 20 elements were determined in the above mentioned samples. Several SRM were irradiated with the samples to insure the reliability of the results.

    Full Text Available Primary pure squamous cell carcinoma (SCC of the gallbladder is an exceptionally rare type of tumor that comprises only 1% of all gallbladder cancer. SCC of the gallbladder portends a worse prognosis than the more common adenocarcinoma variant because of its aggressive invasion to local structures and because it is often diagnosed at an advanced stage. Owing to its rarity, diagnosis and management can be challenging. Herein, we present the case of a 75-year-old female complaining of abdominal pain, nausea, and vomiting. Computed tomography and ultrasonography results of the abdomen were consistent with acute cholecystitis and cholelithiasis. Histologic evaluation of the resected mass revealed a malignant tumor with prominent keratinization, confirming the diagnosis of an invasive primary pure SCC of the gallbladder. Microscopic examination showed direct infiltration to the liver, duodenum, and stomach. This case report describes the hospital course of a patient with SCC of the gallbladder and suggests that gallbladder cancer should be considered as part of the differential diagnosis in elderly patients presenting with acute cholecystitis. In addition, this article will review existing literature to examine the utility of different diagnostic techniques and treatment modalities available in the management of gallbladder cancer.

    Full Text Available The aim of this study was to evaluate the process of biliary excretion of gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA into the biliary tract and to assess the accumulation patterns in the gallbladder using MR cholangiography obtained with Gd-EOB-DTPA which is a liver-specific hepatobiliary contrast agent. Seventy-five patients underwent Gd-EOB-DTPA enhanced MR imaging. Serial multiphasic hepatobiliary phase imaging was qualitatively reviewed to evaluate the process of the biliary excretion of contrast agent into the bile duct and the gallbladder. The accumulation pattern of contrast agent into gallbladder was classified into two groups (group 1 = orthodromic type and group 2 = delayed type. Furthermore, the results in differences of the presence of T1 hyperintense bile or sludge of gallbladder, gall stones, wall thickening of gallbladder, chronic liver disease, and liver cirrhosis between two groups were compared. Forty-eight of 75 patients (64% were included in group 1, and remaining 27 (36% were in group 2. The frequency of the presence of T1 hyperintense bile or sludge of gallbladder was significantly higher in patients with group 2 than that in patients with group 1 (P=0.041. MR cholangiography obtained with Gd-EOB-DTPA showed that there may be an association between the biliary accumulation pattern in the gallbladder and the pathological condition.

    The presence of stones in the common bile duct (CBD) may cause complications such as obstructing jaundice or ascending cholangitis, and the stones should be removed. To assess the efficacy of percutaneous elimination of CBD stones from the gallbladder through the papilla. During a 4 year period, six patients (five men and one woman, mean age 71.5 years) who had CBD stones and an existing gallbladder drain underwent percutaneous stone push into the duodenum after balloon dilatation of the papilla, with a diameter equal to that of the largest stone. Access into the CBD was from the gallbladder, using an already existing percutaneous gallbladder drain (cholecystostomy tube). Each patient had one to three CBD stones measuring 7-14 mm. Successful CBD stone elimination into the duodenum was achieved in five of the six patients. The single failure occurred in a patient with choledochal diverticulum, who was operated successfully. There were no major or minor complications during or after the procedures. Trans-cholecystic CBD stone elimination is a safe and feasible percutaneous technique that utilizes existing tracts, thus obviating the need to create new percutaneous access. This procedure can replace endoscopic or surgical CBD exploration.

    At time of presentation, fewer than 10% of patients have metastatic breast cancer. The most common sites of metastasis in order of frequency are bone, lung, pleura, soft tissue, and liver. Breast cancer metastasis to the uterus or gallbladder is rare and has infrequently been reported in the English literature. A 47 year old female with a recent history of thrombocytopenia presented with abnormal vaginal bleeding. Pelvic ultrasound revealed multiple uterine fibroids and endometrial curettings revealed cells consistent with lobular carcinoma of the breast. Breast examination revealed edema and induration of the lower half of the right breast. Biopsy of the right breast revealed invasive lobular carcinoma. Bone marrow aspiration obtained at a previous outpatient visit revealed extensive involvement by metastatic breast carcinoma. Shortly after discharge, the patient presented with acute cholecystitis and underwent cholecystectomy. Microscopic examination of the gallbladder revealed metastatic infiltrating lobular carcinoma. The final diagnosis was invasive lobular carcinoma of the right breast with metastasis to the bone marrow, endometrium, gallbladder, regional lymph nodes, and peritoneum. The growth pattern of invasive lobular carcinoma of the breast is unique and poses a challenge in diagnosing the cancer at an early stage. Unlike other types of breast cancer, it tends to metastasize more to the peritoneum, ovary, and gastrointestinal tract. Metastasis to the endometrium or gallbladder is rare. Metastatic spread should be considered in the differential diagnosis of patients with invasive lobular breast carcinoma presenting with abnormal vaginal bleeding or acute cholecystitis.

    The prevalence and etiology of the cystic components within gallbladder carcinomas as seen on MR images were evaluated. A retrospective review of MR images was performed for 35 proven gallbladder carcinomas in search of radiologically detectable intratumoral cystic components. The pathologic specimens were meticulously reviewed to determine the etiology. MR images of 31 adenomyomatoses were also reviewed for comparison to clarify the difference in MR features between these two entities. Three cases out of 35 proven gallbladder carcinomas were found to have intratumoral cystic components. They were all well-differentiated adenocarcinomas, and the cystic components consisted of dilated neoplastic glands filled with abundant mucin pool. Adenomyomatosis tended to have more and rounded cystic components (Rokitansky-Aschoff sinuses) lined in a linear fashion and were flat-elevated in shape, smaller in size and had a regular surface, as compared to the three carcinomas. Although rare, radiologists need to be aware that well-differentiated gallbladder carcinoma with mucin production can have cystic components, which may mimic adenomyomatosis. Careful interpretation of MR images may provide useful information in the differentiation of these two entities. (orig.)

    Full Text Available Introduction. Ectopic pelvic liver is an exceedingly rare condition usually resulting after repair of congenital abdominal wall defects. Intrahepatic gallbladder is another rare condition predisposing patients to cholelithiasis and its sequelae. We describe a cholecystectomy in a patient with an intrahepatic gallbladder in a pelvic ectopic liver. Presentation of Case. A 33-year-old woman with a history of omphalocele repair as an infant presented with signs and symptoms of symptomatic cholelithiasis and chronic cholecystitis, however, in an unusual location. After extensive workup and symptomatic treatment, cholecystectomy was recommended and performed via laparotomy and hepatotomy using microwave technology for parenchymal hepatic transection. Discussion. Given the rare combination of an intrahepatic gallbladder and an ectopic pelvic liver, advanced surgical techniques must be employed for cholecystectomies, in addition to involvement of hepatobiliary experienced surgeons due to the distortion of the biliary and hepatic vascular anatomy. Conclusion. Cholecystectomy by experienced hepatobiliary surgeons is a safe and effective treatment for cholecystitis in patients with intrahepatic gallbladders in ectopic pelvic livers.

    Objective: To investigate the relationship between the ultrasonographic changes of gallbladder wall and the hepatic inflammation grading as well as fibrostic staging using ultrasound examination in patients with chronic viral hepatitis, and to survey the diagnostic standard for viral related cholecystitis. Methods: Five hundreds and nineteen chronic viral hepatitis patients and 104 normal control subjects were enrolled in the study. Ultrasound guided liver biopsy was performed in all patients with chronic viral hepatitis, in which the hepatic fibrostic stages(S) were divided into SI (n=148), S2(n=170), S3-4(n 201 ); and hepatic inflammation grades (G) were divided into G1 (n=124 ), G2 (n=204), G3 (n=191). The ultrasound scan was performed within 7 days after liver biopsy. The relationship between ultrasonographic changes of gallbladder and the hepatic inflammation grades and fibrostic stages were analyzed using statistic soft ware SPSS 11.5 for windows. Results: The percentage of the thickened gallbladder wall were 55%, 87%, 96% in S1, S2, S3-4, respectively, and were 45%, 82%, 95% in G1, G2, G3-4, respectively. Significant difference was revealed between G1 and G2, as well as between G2 and G3-4, with P < 0.05. Conclusion: A significant, positive correlative relationship exists between the ultrasonographic changes of gall-bladder wall and the hepatic inflammation grading and fibrostic staging in patients with chronic viral hepatitis.

Gallbladder carcinoma is the most common malignancy of the biliary tract, and is a highly aggressive tumor with an extremely poor prognosis. Unfortunately, the effects of OA on gallbladder carcinoma are unknown. In this study, we investigated the effects of OA on gallbladder cancer cells and the underlying mechanism. The results showed that OA inhibits proliferation of gallbladder cancer cells in a dose-dependent and time-dependent manner on MTT and colony formation assay. A flow cytometry assay revealed apoptosis and G0/G1 phase arrest in GBC-SD and NOZ cells. Western blot analysis and a mitochondrial membrane potential assay demonstrated that OA functions through the mitochondrial apoptosis pathway. Moreover, this drug inhibited tumor growth in nude mice carrying subcutaneous NOZ tumor xenografts. These data suggest that OA inhibits proliferation of gallbladder cancer cells by regulating apoptosis and the cell cycle process. Thus, OA may be a promising drug for adjuvant chemotherapy in gallbladder carcinoma. Keywords: oleanolic acid, gallbladder carcinoma, apoptosis, cell cycle arrest, mitochondrial pathway

    Patients with untreated gallbladder stones in situ are at high risk for late biliary complications after endoscopic papillary balloon dilation (EPBD) and bile duct stone extraction. Few data exist on the short-term and long-term results in these patients after the recurrence of bile duct stones and acute cholecystitis. The aim of this study was to evaluate the outcome of late biliary complications in patients with gallbladder stones in situ after EPBD. Fifty-six patients who developed late biliary complications, including bile duct stone recurrence (n=43) and acute cholecystitis (n=13), were managed at our institutions. We investigated the short-term and long-term outcomes after the management of late biliary complications. Complete removal of recurrent bile duct stones was achieved in 38 of 43 patients (88%) by repeated EPBD alone. Pancreatitis after repeated EPBD occurred in two patients (5%). After successful bile duct stone extraction by EPBD, none of the 16 patients who underwent cholecystectomy developed late biliary complications (mean follow-up period of 5.2 years), whereas re-recurrent bile duct stones occurred in three of the 21 patients (14%) with gallbladder stones left in situ (mean follow-up period of 4.4 years)(P=0.1148). Re-recurrent bile duct stones were successfully treated endoscopically. One of the eight patients who did not undergo cholecystectomy for acute cholecystitis had a recurrence of cholecystitis, which was managed conservatively. The long-term outcomes of late biliary complications are favorable when patients with concomitant gallbladder stones undergo cholecystectomy. Re-recurrent bile duct stones are considerable when gallbladder stones are left in situ, but should be treated endoscopically.

    Introduction Advanced (pT2/T3) incidental gallbladder cancer is often deemed unresectable after restaging. This study assesses the impact of the primary operation, tumour characteristics and timing of management on re-resection. Methods The records of 60 consecutive referrals for incidental gallbladder cancer in a single tertiary centre from 2003 to 2011 were reviewed retrospectively. Decision on re-resection of incidental gallbladder cancer was based on delayed interval restaging at three months following cholecystectomy. Demographics, index cholecystectomy data, primary pathology, CA19–9 tumour marker levels at referral and time from cholecystectomy to referral as well as from referral to restaging were analysed. Results Thirty-seven patients with pT2 and twelve patients with pT3 incidental gallbladder cancer were candidates for radical re-resection. Following interval restaging, 24 patients (49%) underwent radical resection and 25 (51%) were deemed inoperable. The inoperable group had significantly more patients with positive resection margins at cholecystectomy (p=0.002), significantly higher median CA19–9 levels at referral (p=0.018) and were referred significantly earlier (p=0.004) than the patients who had resectable tumours. On multivariate analysis, urgent referral (p=0.036) and incomplete cholecystectomy (p=0.048) were associated significantly with inoperable disease following restaging. Conclusions In patients with incidental, potentially resectable, pT2/T3 gallbladder cancer, inappropriate index cholecystectomy may have a significant impact on tumour dissemination. Early referral of breached tumours is not associated with resectability. PMID:25723690

    Lysine clonixinate (LC) is a non-steroidal antiinflammatory agent (NSAID) with only few adverse effects. This characteristic has prompted us to suggest that its administration, at levels equivalent to those found in human plasma following therapeutic doses, slightly inhibits cyclooxygenase I (COX I). Three experiments were performed. Experiment 1: to study the in vitro effect of LC at concentrations of 4 and 6 micrograms/ml, comparable with those found in plasma following an oral therapeutic dose of 125 mg. Gallbladder tissue segments were incubated with 0.25 microCi of 14C-arachidonic acid and the production of prostaglandin E2 (PGE2), prostaglandin F2 alpha (PGF2 alpha) and 6-keto prostaglandin F1 alpha (6-keto PGF1 alpha) was measured. LC did not affect basal production of any of the 3 prostaglandins (PGs) but at 6 micrograms/ml slightly reduced the levels of 5-hidroxyeicosatetraenoic acid (5-HETE). Experiment 2: LC was administered preoperatively to 6 patients by continuous perfusion, to achieve a steady-state concentration between 4 and 6 micrograms/ml. Gallbladder segments from the 6 treated and another 6 control patients were incubated in 14C-arachidonic acid. Gallbladder segments treated with LC did not show a decreased production of any of the three PGs whereas 5-HETE released to the medium was significantly lower. Experiment 3: 18 patients received an i.v. bolus of LC 100 mg (n1 = 6) or LC 200 mg (n2 = 6) or indomethacin (INDO) 50 mg (n3 = 6). Unlike the administration of INDO bolus, LC in the above doses did not inhibit PG synthesis. Both NSAIDs showed different effects when the production of 5-HETE synthesis was assessed. Treatment with INDO did not alter the production of 5-HETE while LC elicited significant inhibition. The three studies conducted, namely in vitro and in vivo continuous perfusion and i.v. bolus, revealed that LC had no effect on prostaglandin synthesis while reducing significantly the levels of 5-HETE.

  18. Bovine somatic cell nuclear transfer.

    Somatic cell nuclear transfer (SCNT) is a technique by which the nucleus of a differentiated cell is introduced into an oocyte from which its genetic material has been removed by a process called enucleation. In mammals, the reconstructed embryo is artificially induced to initiate embryonic development (activation). The oocyte turns the somatic cell nucleus into an embryonic nucleus. This process is called nuclear reprogramming and involves an important change of cell fate, by which the somatic cell nucleus becomes capable of generating all the cell types required for the formation of a new individual, including extraembryonic tissues. Therefore, after transfer of a cloned embryo to a surrogate mother, an offspring genetically identical to the animal from which the somatic cells where isolated, is born. Cloning by nuclear transfer has potential applications in agriculture and biomedicine, but is limited by low efficiency. Cattle were the second mammalian species to be cloned after Dolly the sheep, and it is probably the most widely used species for SCNT experiments. This is, in part due to the high availability of bovine oocytes and the relatively higher efficiency levels usually obtained in cattle. Given the wide utilization of this species for cloning, several alternatives to this basic protocol can be found in the literature. Here we describe a basic protocol for bovine SCNT currently being used in our laboratory, which is amenable for the use of the nuclear transplantation technique for research or commercial purposes.

    We report the successful conversion of percutaneous cholecystostomy (PC) to endoscopic transpapillary gallbladder stenting (ETGS) with insertion of an antegrade guidewire into the duodenum. An 84-year-old man presented with severe acute cholecystitis and septic shock. He had significant comorbidities, and emergent PC was successfully performed. Subsequent ETGS was attempted but unsuccessful owing to difficulties with cystic duct cannulation. However, via the PC tract, the guidewire was passed antegradely into the duodenum, and ETGS with a double-pigtail plastic stent was successfully performed with the rendezvous technique. The PC tube was removed, and no recurrence was reported during the 17-month follow-up period. Conversion of PC to ETGS is a viable option in patients with acute cholecystitis who are not candidates for surgery. Antegrade guidewire insertion via the PC tract may increase the success rate of conversion and decrease the risk of procedure-related complications.

    Early diagnosis and accurate staging of carcinomas of the gallbladder and the bile ducts are helpful in improving the prognosis. Ultrasonography (US), a useful initial modality when exploring the background of jaundice or non-specific gastrointestinal complaints, sensitively reveals bile duct obstruction in particular. In unclear cases, or if US suggests a resectable biliary malignancy, computed tomography (CT), magnetic resonance imaging (MRI) with magnetic resonance cholangiography (MRC) and/or traditional cholangiography often provide additional information, and imaging-guided fine-needle biopsy or an endoscopic brush sample may verify the malignant nature of the tumor. Complementary modalities are usually needed for accurate staging, and traditional cholangiography is often performed for therapeutic purposes as well. Comparative studies of MRI with MRC and multidetector CT in biliary cancers would be welcome.

    A new, simple, non-invasive external scintillation counting technique has been developed to directly assess changes in gallbladder volume - quantitative sup(99m)Tc-pyridoxylidene glutamate scintiscanning. From an experience of several hundred sup(99m)Tc-pyridoxylidene glutamate cholescintiscans, interpretive criteria have been established for the confirmation or exclusion of a diagnosis of acute cholecystitis in patients who present with acute 'biliary' pain. The fasting period, the appearance and timing of scintiscans, the serum amylase and bilirubin, have all been shown to be important. These interpretive criteria have been used in a prospective study on 121 patients admitted as an emergency with a clinical diagnosis of acute cholecystitis or biliary colic. This study revealed that the investigation of choice to confirm a clinical diagnosis of acute cholecystitis was sup(99m)Tc-pyridoxylidene glutamate cholescintigraphy because it was evaluable in 99% of patients and had a sensitivity of 99% and a specificity of 91%.

    Percutaneous transhepatic access to the bile duct has opened up new possibilities not only for diagnosis by means of cholangiography and cholangioscopy with endoscopically guided biopsy by small-bore equipment, but also for the treatment of benign and malignant obstructive jaundice. In malignant disease recanalization of the obstruction is possible by means of laser, intracavitary irritation, internal bile drainage in Klatskin tumors, large-diameter endoprostheses (e.g., a Y-shaped prosthesis) or metal stents. In benign disease, balloon dilatation of inflammatory stenoses, stone extractions from the bile duct or gallbladder by means of Dormia baskets, ultrasound or pezo electric shockwave-contact lithotripsy and chemical litholysis are possible very often percutaneous access is a real alternative to surgical intervention.

    Ectopic liver tissue is a rare clinical entity that is mostly asymptomatic and found incidentally. In certain situations, however, patients may present with symptoms of abdominal pain secondary to torsion, compression, obstruction of adjacent organs, or rupture secondary to malignant transformation. Herein, we report a case of a 25-year-old female that presented with acute onset of epigastric pain found to have ectopic liver tissue near the gallbladder complicated by acute hemorrhage necessitating operative intervention in the way of laparoscopic excision and cholecystectomy. The patient\\'s postoperative course was uneventful. Gross pathology demonstrated a 1.2 x 2.8 x 4.5 cm firm purple ovoid structure that histologically revealed extensive hemorrhagic necrosis of benign ectopic liver tissue.

All procedures were technically successful, and no major procedure-related complications occurred. Eight patients (80%) responded favorably to PC. One, who did not respond, underwent emergency cholecystectomy next day due to worsening peritonitis, and the other who failed to respond within 72hr showed delayed response after drainage of a coexistent liver abscess at seven days after the procedure. A patient who responded to PC experience catheter dislodgement four days after the procedure but reinsertion was not required. Five of eight patients who responded positively underwent elective cholecystecomy after the improvement of clinical symptoms, and the three remaining patients improved without further surgery.

    In an effort to overcome the limitations of single-port laparoscopic cholecystectomy (LC) while preserving the cosmetic benefits of reduced ports cholecystectomy, we have developed a 2-port LC that allows for the full, unrestricted use of 4 laparoscopic instruments. We retrospectively analyzed data of patients who had undergone either 4-port LC or 2-port LC for benign gallbladder diseases between March 2007 and March 2013. Two incisions of 2-port LC were composed of an umbilical incision as the manner of single-port laparoscopic surgery and a 5-mm epigastric incision. These two incisions were utilized for comfortable bimanual manipulation under the liver-elevated vision provided by a liver retractor. During the study period, 766 patients underwent LC; 263 (34.3%) started with 4-port LC, and 503 (65.7%) started with 2-port LC. Of patients started with 2-port LC, 486 patients (96.6%) was ended up with 2-port without open conversion or addition of port(s). The two groups had similar operative time, open conversion rate, incidence of complications, analgesic requirement, and length of postoperative hospital stay. Multivariate analyses revealed that the independent factors related to prolonged operative time (≥ 90 th percentile) in 2-port LC were the presence of cholecystitis (odds ratio [OR] 2.412, 95% CI 1.246-4.668, p = 0.009) and admission through the emergency department (OR 2.132, 95% CI 1.135-4.004, p = 0.019). This study suggests that 2-port LC for benign gallbladder diseases is as safe and feasible as 4-port LC when it is performed by surgeons trained in conventional laparoscopic techniques.

    Full Text Available Abstract Background Only 50% of gallbladder cancers (GBC are recognized before operation and the remaining tumors are diagnosed during surgery or afterwards by the pathologist. These situations may demand substantial modifications of the proceeding during surgery as well as the need for reoperation in some cases. Therefore, the time of diagnosis may strongly influence the surgical management of GBC and the prognosis of the patients. Methods Records and follow-up of 152 patients with gallbladder carcinoma who underwent surgery between 1980 and 2004 were examined according to the time of diagnosis, TNM staging system, surgical procedures, morbidity and predictors of survival. There were 76 patients with preoperative diagnosis of GBC (50%; group1, 44 patients with intraoperative diagnosis (29%; group 2 and 32 patients (21%; group 3 with postoperatively incidental finding of GBC. In all cases radical resection of the GBC was intended, except in 5 patients from group 1. Surgical procedures comprised from simple cholecystectomy to multivisceral resections. Results Overall 5-year survival rate was 7% with a significantly better median survival in group 3 (53.2 month, when compared to only 6.1 month (group 2 and 5.4 month (group 1, respectively. Findings at operation forced significant modifications of the surgical strategy in 85%. Complete resection of GBC was achieved in 38% of the patients. Stage- dependent survival was comparable between the groups following R0 resection. Tumor stage, in particular the nodal status and radicality of the procedure, but not the time of diagnosis were the most powerful predictors of outcome. Conclusions Complete tumor resection may provide long-term survival even in locally advanced GBC. Although the time of diagnosis of GBC causes significant changes of the intended procedures during and after surgery, it has no influence on the prognosis provided that radical (R0 resection was accomplished.

    To meta-analyze published data about the diagnostic accuracy of fluorine-18-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) and PET/computed tomography (PET/CT) in the evaluation of primary tumor in patients with gallbladder cancer (GBCa). A comprehensive literature search of studies published through 30(th) June 2014 regarding the role of (18)F-FDG PET and PET/CT in the evaluation of primary gallbladder cancer (GBCa) was performed. All retrieved studies were reviewed. Pooled sensitivity and specificity of (18)F-FDG PET or PET/CT in the evaluation of primary GBCa were calculated. The area under the summary receiving operator characteristics curve (AUC) was calculated to measure the accuracy of these methods. Sub-analyses considering the device used (PET vs PET/CT) were carried out. Twenty-one studies comprising 495 patients who underwent (18)F-FDG PET or PET/CT for suspicious GBCa were selected for the systematic review. The meta-analysis of 13 selected studies provided the following results: sensitivity 87% (95%CI: 82%-92%), specificity 78% (95%CI: 68%-86%). The AUC was 0.88. Improvement of sensitivity and specificity was observed when PET/CT was used. (18)F-FDG-PET and PET/CT demonstrated to be useful diagnostic imaging methods in the assessment of primary tumor in GBCa patients, nevertheless possible sources of false-negative and false-positive results should be kept in mind. PET/CT seems to have a better diagnostic accuracy than PET alone in this setting.

    OBJECTIVE: This study aimed to reveal the risk factors and outcomes of gallbladder perforation (GP) during laparoscopic cholecystectomy. METHODS: Videotapes of all patients who underwent an elective cholecystectomy at our department were retrospectively analyzed, and the patients were divided into two groups based on the presence of GP. The possible risk factors and early outcomes were analyzed. RESULTS: In total, 664 patients [524 (78.9%) females, 49.7±13.4 years of age] were observed, and GP occurred in 240 (36.1%) patients, mostly while dissecting the gallbladder from its bed (n=197, 82.1%). GP was not recorded in the operation notes in 177 (73.8%) cases. Among the studied parameters, there was no significant risk factor for GP, except preoperatively elevated alanine transaminase level (p=0.005), but the sensitivity and specificity of this measure in predicting GP were 14.2% and 7.4%, respectively. The two groups had similar outcomes, but the operation time (35.4±17.5 vs 41.4±18.7 min, p=0.000) and incidence of drain use (25% vs 45.8%, p=0.000) increased in the GP group. CONCLUSION: The present study reveals that GP occurs in 36.1% of patients who undergo laparoscopic elective cholecystectomy, but it may not be recorded in most cases. We did not find any reliable risk factor that increases the possibility of GP. GP causes an increase in the operation time and incidence of drain use; however, the other outcomes were found to be similar in patients with GP and those without. PMID:29607432

He was treated with melphalan, prednisone, and zoledronic acid, with a good response. However, he had severe anemia, and endoscopic examination revealed gastric cancer. He died 3 months later. Autopsy revealed verrucous gastric cancer consisting of numerous polypoid mucosal excrescences that had metastasized to the gallbladder and urinary bladder, showing similar polypoid mucosal lesions. The cancer consisted of poorly differentiated cells (about 85% and signet ring cells (15% in the stomach. The cancerous tissue was not associated with a desmoplastic reaction, and the signet ring cells showed a positive reaction to cytokeratin 7 and regenerating islet-derived family member 4 antibodies. The cancer cells had a propensity to proliferate on the mucosal surface of the stomach, gallbladder, and urinary bladder.

    Carcinoma of the gallbladder is often missed because of the low index of suspicion. To review the incidence, pattern and outcome of carcinoma of the gallbladder in our center and to highlight the need for early diagnosis. Retrospective survey of all cases of carcinoma of the gallbladder. Nnamdi Azikiwe University Teaching Hospital serving rural, semi-urban and urban communities. Patients who had histologically confirmed carcinoma in the general surgical units of the Nnamdi Azikiwe University Teaching Hospital over a 5-year period were reviewed and, from their case notes, the following information on sex, age, mode of presentation, time of diagnosis, stage of disease, treatment given and outcome were extracted. Twenty-one cases of gallbladder carcinoma were seen out of a total of 692 cases of different types of cancers seen in the general surgical units, giving an incidence of 3.04%. Six were males and 15 were females, age ranged between 39 and 72 years, a mean of 55; with the peak age in the 7th decade of life. Eleven patients (52.4%) presented with features of chronic cholecystitis and had cholecystectomy. Ten patients presented with obstructive jaundice in a stage too advanced for any form of palliative surgical treatment. The outcome was good in patients who presented with features of cholecystitis but who turned out to be cases of early carcinoma of the gallbladder because after five years of follow-up, none of them has shown any features of recurrence. There was no mortality in this group and the patients have remained in good health. However, the prognosis was poor in those patients who presented with obstructive jaundice. They remained very ill, with worsening general condition. They were discharged home on request of their relations and were lost to follow-up. Carcinoma of the gallbladder may present as cholecystitis. It is advisable for clinicians to have this in mind before, during and after cholecystectomy. Early presentation to hospital by patients

    To study the c-Kit expression in the gallbladder of cholesterol lithogenic guinea pig model and the effect of Artemisia capillaris Thunb on interstitial cells of Cajal (ICCs). A total of 45 guinea pigs were randomly assigned into three groups: the control group (guinea pigs fed a standard diet, normal group); the model group (guinea pigs fed a cholesterol gallstone-inducing diet); and the Chinese medicine group (guinea pigs fed the cholesterol gallstone-inducing diet and treated with A. capillaris through intragastric administration, therapy group). Each group had 15 guinea pigs. The gallbladders of the guinea pigs were harvested after 8 weeks. C-Kit expression was detected using an immunohistochemistry staining, real-time PCR, and Western blot analyses. The effect of A. capillaris on ICCs was evaluated by muscle strip contraction experiments. C-Kit expression significantly decreased in the gallbladder of model group, but increased in the Chinese medicine group. The Contractility of guinea pig gallbladder muscle strip significantly improved in the Chinese medicine group. Our results indicated that A. capillaris improves gallbladder impairment by up-regulating c-Kit expression, and it also can improve the contractile response of in vitro guinea pig gallbladder muscle strips.

    The major objectives of this project were to establish the pattern of basal hepatic bile flow and the effects of intravenous administration of cholecystokinin on the liver, sphincter of Oddi, and gallbladder, and to identify reliable parameters for the diagnosis of sphincter of Oddi spasm (SOS). Eight women with clinically suspected sphincter of Oddi spasm (SOS group), ten control subjects (control group), and ten patients who had recently received an opioid (opioid group) were selected for quantitative cholescintigraphy with cholecystokinin. Each patient was studied with 111-185 MBq (3-5 mCi) technetium-99m mebrofenin after 6-8 h of fasting. Hepatic phase images were obtained for 60 min, followed by gallbladder phase images for 30 min. During the gallbladder phase, 10 ng/kg octapeptide of cholecystokinin (CCK-8) was infused over 3 min through an infusion pump. Hepatic extraction fraction, excretion half-time, basal hepatic bile flow into the gallbladder, gallbladder ejection fraction, and post-CCK-8 paradoxical filling (>30% of basal counts) were identified. Seven of the patients with SOS were treated with antispasmodics (calcium channel blockers), and one underwent endoscopic sphincterotomy. Mean (±SD) hepatic bile entry into the gallbladder (versus GI tract) was widely variable: it was lower in SOS patients (32%±31%) than in controls (61%±36%) and the opioid group (61%±25%), but the difference was not statistically significant. Hepatic extraction fraction, excretion half-time, and pattern of bile flow through both intrahepatic and extrahepatic ducts were normal in all three groups. Gallbladder mean ejection fraction was 9%±4% in the opioid group; this was significantly lower (P<0.0001) than the values in the control group (54%±18%) and the SOS group (48%±29%). Almost all of the bile emptied from the gallbladder refluxed into intrahepatic ducts; it reentered the gallbladder after cessation of CCK-8 infusion (paradoxical gallbladder filling) in all eight

    The porcelain is composed of feldspar, kaolin and about 50% for bovine bone ashes. This work aims to analyze the properties acquired by the substitution of kaolin by its waste. For characterization of raw materials chemical analyzes were made by X-Ray Fluorescence (XRF) and mineralogical analysis by X-Ray Diffraction (XRD). Four formulations were produced varying the percentage of waste materials of kaolin and bone ashes of 25 and 55% by weight. The samples were sintered at temperatures of 1150, 1200 and 1250 deg C. The technological tests realized were: water absorption (WA), apparent porosity (AP), apparent density (AD) and linear retraction (LR). Improvement in the physical-mechanical properties of the samples with increasing temperature were observed, and 1250 deg C obtained 0.69% of WA, 1.22% AP, 2.26 g / cm3 AD, and 0.52% LR

    Mastitis is one of the most prevalent and costly diseases in the dairy industry with losses attributable to reduced milk production, discarded milk, early culling, veterinary services, and labor costs. Typically, mastitis is an inflammation of the mammary gland most often, but not limited to, bacterial infection, and is characterized by the movement of leukocytes and serum proteins from the blood to the site of infection. It contributes to compromised milk quality and the potential spread of antimicrobial resistance if antibiotic treatment is not astutely applied. Despite the implementation of management practises and genetic selection approaches, bovine mastitis control continues to be inadequate. However, some novel genetic strategies have recently been demonstrated to reduce mastitis incidence by taking advantage of a cow’s natural ability to make appropriate immune responses against invading pathogens. Specifically, dairy cattle with enhanced and balanced immune responses have a lower occurrence of disease, including mastitis, and they can be identified and selected for using the high immune response (HIR) technology. Enhanced immune responsiveness is also associated with improved response to vaccination, increased milk, and colostrum quality. Since immunity is an important fitness trait, beneficial associations with longevity and reproduction are also often noted. This review highlights the genetic regulation of the bovine immune system and its vital contributions to disease resistance. Genetic selection approaches currently used in the dairy industry to reduce the incidence of disease are reviewed, including the HIR technology, genomics to improve disease resistance or immune response, as well as the Immunity+™ sire line. Improving the overall immune responsiveness of cattle is expected to provide superior disease resistance, increasing animal welfare and food quality while maintaining favorable production levels to feed a growing population.

    Full Text Available Introduction. The incidence of gallbladder cancer presenting with acute cholecystitis is 2.3%, squamous cell carcinoma is rarely seen, and overlap of acute cholecystitis and squamous cell carcinoma is a very rare condition in the literature. Presentation of Case. A 75-year-old woman was admitted to emergency service with a pain in the right upper quadrant, nausea, and vomiting. The patient was considered as having acute cholecystitis. During the exploration because Hartman’s pouch was not dissected, it was adhered to the cystic duct and had fibrotic adhesion. It could not be understood whether this adhesion was a tumor or a fibrotic tumor and thus we performed cholecystectomy with a 1 cm resection of the choledochus. Pathological examination revealed the presence of (R0, T1 N0 M0 squamous cell carcinoma with clean resection borders and there was no in tumor five dissected lymph nodes. The patient has been followed up for about two years and no clinical problem has been observed throughout the follow-up. Discussion. Acute cholecystitis with gallstones may overlap with gallbladder cancer and generally presents nonspecific symptoms. No additional imaging techniques were performed since no clinical sign except for the wall thickening was detected and no suspected malignancy such as mass was detected on USG. Squamous cell carcinoma of the gallbladder shows poor diagnosis, but since its overlap with cholecystitis presents early symptoms and thus leads to early diagnosis and effective treatment, the localization of the carcinoma is of prime importance. Conclusion. Gallbladder cancer should be kept in mind in elderly patients with acute cholecystitis.

    Gallbladder cancer is a rare cancer with a poor prognosis, and few risk factors have been identified to date. This prospective study was conducted to evaluate the association of cigarette smoking and alcohol consumption with the risk of gallbladder cancer death. A baseline survey in 45 areas throughout Japan was conducted from 1988 to 1990 using a self-administered questionnaire, and a total of 113,496 participants (65,740 women) aged 40-89 years at entry were followed for 15 years. During the follow-up period, 165 gallbladder cancer deaths (95 women) were observed. Among women, the hazard ratio (HR) [95 percent confidence interval: 95% CI] of current smoker was 2.00 [0.91-4.42], when adjusted for age and drinking. There was no clear association between alcohol consumption and the risk. Among men, HR of current smoker was 2.27 [1.05-4.90]. HRs of those who smoked 21 cigarettes or more per day and those with 801-1,000 cigarette-years were 3.18 [1.18-8.53] and 3.44 [1.40-8.45], respectively, and positive linear associations were observed between that risk and the number of cigarettes per day (p for trend = 0.007) or "cigarette-years" (p for trend = 0.012). The alcohol dose was linearly associated with risk (p for trend = 0.004), where the HR among those who consumed 72.0 g or more of alcohol per day was 3.60 [1.29-9.85]. Among both men and women, cigarette smoking may elevate the risk of death from gallbladder cancer. Drinking may pose an elevated risk among men, but that seems to be less true among women.

    To investigate the relationship between Clonorchis sinensis infection and the gallbladder stone type in patients with cholelithiasis in the endemic area of clonorchiasis. Gallbladder stones were collected from 598 patients with cholelithiasis through minimally invasive gallbladder-preserving cholelithotomy in the Sixth People's Hospital of Nansha District from May 2009 to October 2012. The stone samples were analyzed for composition by Fourier transform infrared spectroscopy to identify their types. The Clonorchis sinensis eggs were detected in the stones by microscopic examination, and the detection rates of eggs were calculated for different stone types. Then the clinical characteristics and biochemical indicators were compared among patients with different types of stones, as well as between Clonorchis sinensis egg-positive and -negative patients with the calcium-carbonate type of stones. Some calcium-carbonate stones positive for Clonorchis sinensis eggs were randomly selected for further scanning electron microscopy (SEM) examination. Of the stones from 598 patients, 234 (39.1%) were cholesterol type, 133 (22.2%) bile pigment type, 112(18.7%) calcium-carbonate type, 86 (14.4%) mixed types and 33(5.5%) were others. The detection rate of Clonorchis sinensis eggs in these types was 6% (15/234), 44% (59/133), 60% (67/112), 36% (31/ 86) and 30% (10/33), respectively, being highest in calcium-carbonate stones while lowest in cholesterol stones. The Co2-combining power of the plasma was higher in patients with calcium-carbonate and mixed stones than in those with cholesterol stones (P Clonorchis sinensis eggs to calcium-carbonate crystals. The infection rate of Clonorchis sinensis is higher in patients with calcium-carbonate gallbladder stones than in those with other types of stones.

    SUMMARY The paper presents data from a study of the neuroendocrine regulation of nonstriated muscles, bronchial tree and the gallbladder tones by means of an assessment of the adrenergic and cholinergic systems state in patients, suffering from chronic obstructive pulmonary disease and chronic acalculous cholecystitis. Adrenergic and cholinergic activities as well as cortisol secretion have significantly changed. To study the features of adrenergic and cholinergic regulations of bronchial tone and that of the gallbladder in patients with combined course of chronic acalculous cholecystitis and chronic obstructive pulmonary disease. 92 patients were involved in the study: 30 patients with COPD (1st group), 30 patients with COPD of comorbid CAC in the acute phase (2nd group), 32 patients with CAC in the acute phase (3rd group) and a control group--30 practically healthy individuals (PHI) of the respective age. All the patients with COPD and COPD combined with CAC had a marked predominance of the parasympathetic nervous system, as evidenced by the established significant decrease of CDE (Table) in patients with isolated COPD is 1.4 times (p instance, the CDA in the individuals of groups 1 and 2 was lower by 1.6 and 2.4 times respectively (p instance, the first group patients' blood contained 2.7 times (p base of regulatory neuroendocrine and paracrine mecganisms imbalance, contributing to a development of COPD, is the cholinergic imbalance (reduction in blood acetylcholinesterase activity, hypertensive sphincter of Oddi dysfunction), adrenergic imbalance, reduction in catecholamine-depositing erythrocytes function, hypokinetic gallbladder dysfunction, adrenal dysfunction (decreased cortisol levels) that contribute to the development and progression of chronic cholecystitis against a background of hypokinetic gallbladder dysfunction.

    In the present study, the effects of ionizing radiation of Cs-137 and Co-60 from 4.95 to 743.14 Gy and from 40 Gy to 300 kGy, respectively, on some bovine hemoglobin characteristics were studied. Such an effect was evaluated using electron paramagnetic resonance (EPR) spectroscopy, and infra-red (IR) spectroscopy. Bovine hemoglobin EPR spectra were recorded and analyzed before and after irradiation and changes were explained in detail. IR spectra of unirradiated and irradiated Bovine hemoglobin were recorded and analyzed also. It was found that ionizing radiation may lead to the increase of free radicals production, the decrease in α-helices contents, which reflects the degradation of hemoglobin molecular structure, or at least its incomplete performance. Results also show that the combined application of EPR and FTIR spectroscopy is a powerful tool for determining structural modification of bovine hemoglobin samples exposed to gamma irradiation

    Full Text Available In the English literature, only 9 cases of adenocarcinoma of the gallbladder with cutaneous metastasis have been reported so far. One case of multiple cutaneous metastases along with deposits in the breast tissue has been reported. We present a case of incidental metastatic gallbladder carcinoma with no intra-abdominal disease presenting as a series of four isolated cutaneous right chest wall, axillary nodal, breast and pulmonary metastases following resection and adjuvant chemoradiation for her primary tumor. In spite of the metastatic disease coupled with the aggressive nature of the cancer, this patient reported that her energy level had returned to baseline with a good appetite and a stable weight indicating a good performance status and now is alive at 25 months since diagnosis. Her serially-presented, oligometastatic diseases were well-controlled by concurrent chemoradiation and stereotactic radiation therapy. We report this case study because of its rarity and for the purpose of complementing current literature with an additional example of cutaneous metastasis from adenocarcinoma of the gallbladder.

    Full Text Available Objective: To study the effect of integrated surgery + radiotherapy + chemotherapy treatment on the survival status and serum indexes in patients with gallbladder carcinoma. Methods: A total of 68 patients with gallbladder carcinoma were divided into observation group (received integrated surgery + radiotherapy + chemotherapy treatment and control group (received surgery + radiotherapy according to different treatments. Differences in the content of tumor markers, growth factors and adhesion molecules in serum as well as the median survival time and survival rate in 5 years of follow-up were compared between the two groups 1 month after treatment. Results: Tumor markers β2-MG, CA19-9, CA242, CA125, CA724, CEA and AFP content in serum of observation group after treatment were significantly lower than those of control group; growth factors VEGF, FGF, EGFR and HER2 content in serum were significantly lower than those of control group while IGFBP-2 and IGFBP-3 content were significantly higher than those of control group; adhesion molecules E-selectin, ICAM-1, VCAM-1 and sE-Cd content in serum were significantly lower than those of control group; the median survival time of 5-year follow-up as well as 1-, 3- and 5-year survival rate were significantly greater than those of control group. Conclusions: Integrated treatment of surgery + radiotherapy + chemotherapy can optimize the short-term and long-term curative effect in patients with gallbladder carcinoma.

After 12 months of treatment, stone dissolution was found in 9 (40.9% of the patients in group I and 7 (38.8% of the patients in group II. The difference was statistically significant compared to controls in both treatment groups (0.05. All the patients that achieved dissolution had multiple gallstones except for one patient with a solitary stone in group I. Neither monotherapy of UDCA nor the combination with domperidone affected the ejection fraction of gallbladder. Conclusions. Combination with domperidone did not potentiate the efficacy of UDCA. It has been observed that both UDCA alone and UDCA plus domperidone treatment did not affect ejection fraction of gallbladder.

    The aims of the study were to describe the dynamics of the enterohepatic circulation in relation to gallbladder and gastrointestinal motility in the interdigestive as well as the postprandial period. Furthermore, to investigate the level of circulating cholecystokinin, secretin, pancreatic polypeptide, motilin and bile acids in relation to gallbladder motility and MMC during the interdigestive period. All investigations were carried out on healthy male volunteers aged 18-40 years. The most suitable method for studying various characteristics of the enterohepatic circulation, and especially gallbladder motility in humans, is scintigraphy. It is non-invasive, and allows a continuing dynamic investigation of the partitioning of the radioactive marker between the various compartment. Two entirely different pharmacological substances may be use. HIDA (diethyl-acetanilide-iminodiacetic acid) which is semisynthetic and closely related to lidocaine forms a chelate with 99m Tc for intravenous administration only. The transport of 99m Tc-HIDA across the hepatocyte is a carrier-mediated organic anion pathway, similar to the hepatic handling of bilirubin. Homocholic-acid-taurine (HCAT) is a synthetic bile acid analogue, corresponding to the naturally occurring bile acid cholic acid-taurine. It is marked with 75 Se and is available for peroral use only. The 75 SeHCAT is adsorbed in the same manner as the naturally occurring conjugated trihydroxy bile acids, involving specific carrier systems for absorption and secretion, i.e. with a high first pass extraction and a secretory rate proportional to the blood concentration.

    Full Text Available Abstract Introduction Injury of the gallbladder after blunt abdominal trauma is an unusual finding; the reported incidence is less than 2%. Three groups of injuries are described: simple contusion, laceration, and avulsion, the last of which can be partial, complete, or total traumatic cholecystectomy. Case presentation A case of isolated complete avulsion of the gallbladder (near traumatic cholecystectomy from its hepatic bed in a 46-year-old Caucasian man without any other sign of injury is presented. The avulsion was due to blunt abdominal trauma after a car accident. The rarity of this injury and the stable condition of our patient at the initial presentation warrant a description. The diagnosis was made incidentally after a computed tomography scan, and our patient was treated successfully with ligation of the cystic duct and artery, removal of the gallbladder, coagulation of the bleeding points, and placement of a drain. Conclusions Early diagnosis of such injuries is quite difficult because abdominal signs are poor, non-specific, or even absent. Therefore, a computed tomography scan should be performed when the mechanism of injury is indicated.

    Brucellosis is a globally important zoonotic infectious disease caused by gram negative bacteria of the genus Brucella. While many species of Brucella exist, Brucella melitensis, Brucella abortus, and Brucella suis are the most common pathogens of humans and livestock. The virulence of Brucella is largely influenced by its ability to evade host factors, including phagocytic killing mechanisms, which are critical for the host response to infection. The aim of this study was to characterize the bovine neutrophil response to virulent Brucella spp. Here, we found that virulent strains of smooth B. abortus, B. melitensis, B. suis, and virulent, rough, strains of Brucella canis possess similar abilities to resist killing by resting, or IFN-γ-activated, bovine neutrophils. Bovine neutrophils responded to infection with a time-dependent oxidative burst that varied little between Brucella spp. Inhibition of TAK1, or SYK kinase blunted the oxidative burst of neutrophils in response to Brucella infection. Interestingly, Brucella spp. did not induce robust death of bovine neutrophils. These results indicate that bovine neutrophils respond similarly to virulent Brucella spp. In addition, virulent Brucella spp., including naturally rough strains of B. canis, have a conserved ability to resist killing by bovine neutrophils.

    Cryptosporidium parvum (C. parvum) is an intestinal parasite that causes diarrhea in neonatal calves. It results in significant morbidity of neonatal calves and economic losses for producers worldwide. Innate resistance against C. parvum is thought to depend on engagement of pattern recognition receptors. However, the role of innate responses to C. parvum has not been elucidated in bovine. The aim of this study was to evaluate the role of TLRs in host-cell responses during C. parvum infection of cultured bovine intestinal epithelial cells. The expressions of TLRs in bovine intestinal epithelial cells were detected by qRT-PCR. To determine which, if any, TLRs may play a role in the response of bovine intestinal epithelial cells to C. parvum, the cells were stimulated with C. parvum and the expression of TLRs were tested by qRT-PCR. The expression of NF-κB was detected by western blotting. Further analyses were carried out in bovine TLRs transfected HEK293 cells and by TLRs-DN transfected bovine intestinal epithelial cells. The results showed that bovine intestinal epithelial cells expressed all known TLRs. The expression of TLR2 and TLR4 were up-regulated when bovine intestinal epithelial cells were treated with C. parvum. Meanwhile, C. parvum induced IL-8 production in TLR2 or TLR4/MD-2 transfected HEK293 cells. Moreover, C. parvum induced NF-κB activation and cytokine expression in bovine intestinal epithelial cells. The induction of NF-κB activation and cytokine expression by C. parvum were reduced in TLR2-DN and TLR4-DN transfected cells. The results showed that bovine intestinal epithelial cells expressed all known TLRs, and bovine intestinal epithelial cells recognized and responded to C. parvum via TLR2 and TLR4.

    To evaluate the safety and efficacy of radiofrequency (RF) ablation for treatment of focal hepatic lesions adjacent to the gallbladder with electrode relocation and ablation time reduction. Thirty-nine patients who underwent RF ablation for focal hepatic lesions adjacent to the gallbladder (≤ 10 mm) were evaluated retrospectively from January 2011 to December 2014 (30 men and 9 women; age range, 51-85 y; mean age, 65 y). Of 36 patients with hepatocellular carcinoma, 3 had a second treatment for recurrence (mean tumor size, 15 mm ± 6). Patients were divided into 2 subgroups based on lesion distance from the gallbladder: nonabutting (> 5 mm; n = 19) and abutting (≤ 5 mm; n = 20). Electrodes were inserted parallel to the gallbladder through the center of a tumor in the nonabutting group and through the center of the expected ablation zone between a 5-mm safety zone on the liver side and the gallbladder in the abutting group. Ablation time was decreased in proportion to the transverse diameter of the expected ablation zone. Technical success and technical effectiveness rates were 89.7% and 97.4%, respectively, with no significant differences between groups (P = 1.00). Local tumor progression was observed in 3 patients (1 in the nonabutting group and 2 in the abutting group; P = 1.00). There were no major complications. The gallbladder was thickened in 10 patients, with no significant difference between groups (P = .72). Biloma occurred in 1 patient in the nonabutting group. RF ablation with electrode relocation and reduction of ablation time can be a safe and effective treatment for focal hepatic lesions adjacent to the gallbladder. Copyright © 2017 SIR.

    The eventual relation between biliary lithiasis and chronic pancreatitis (CP) has been studied before but the research on the gallbladder involvement in chronic pancreatitis patients are rare, specially from a functional point of view. In order to study that, gallbladder emptying was evaluated in 11 patients with CP and the results were compared and analyzed statistically with the ones observed in 10 controls. This series exclude patients and controls who presented any kind of prior or current affection, or condition, that could interfere with the gastric or gallbladder emptying and the release of the entero pancreatic hormones. Gallbladder emptying was studied through the scintillographic method, using Tc-99m DISIDA, through the calculation of the ejection (EF) of the gallbladder (GB), at 30, 45 and 60 minutes. In the patients this evaluation was studied in two different periods of time with an interval of two to four weeks between them, without (CPWOP) and with (CPWP) the addition of pancreatic extract. The analyses of the results disclosed that the EF of GB at 60 minutes was significantly higher in the controls when compared tro chronic pancreatopaths. On the other hand, the EF of GB in these patients did not show any statistically significant differences after the administration of pancreatic extract. The results suggest that the delay in the gallbladder emptying does not depend exclusively on the eventual alteration in the intestinal phase of the gallbladder stimulation, but it probably also results from the association with other factors involved, as a mechanic factor, which depends on the compression of the main biliary tract through the chronic pathological process located in the cephalic portion of the pancreas.

    Full Text Available Blockade of immunoinhibitory molecules, such as programmed death-1 (PD-1/PD-ligand 1 (PD-L1, is a promising strategy for reinvigorating exhausted T cells and preventing disease progression in a variety of chronic infections. Application of this therapeutic strategy to cattle requires bovinized chimeric antibody targeting immunoinhibitory molecules. In this study, anti-bovine PD-1 rat–bovine chimeric monoclonal antibody 5D2 (Boch5D2 was constructed with mammalian expression systems, and its biochemical function and antiviral effect were characterized in vitro and in vivo using cattle infected with bovine leukemia virus (BLV. Purified Boch5D2 was capable of detecting bovine PD-1 molecules expressed on cell membranes in flow cytometric analysis. In particular, Biacore analysis determined that the binding affinity of Boch5D2 to bovine PD-1 protein was similar to that of the original anti-bovine PD-1 rat monoclonal antibody 5D2. Boch5D2 was also capable of blocking PD-1/PD-L1 binding at the same level as 5D2. The immunomodulatory and therapeutic effects of Boch5D2 were evaluated by in vivo administration of the antibody to a BLV-infected calf. Inoculated Boch5D2 was sustained in the serum for a longer period. Boch5D2 inoculation resulted in activation of the proliferation of BLV-specific CD4+ T cells and decrease in the proviral load of BLV in the peripheral blood. This study demonstrates that Boch5D2 retains an equivalent biochemical function to that of the original antibody 5D2 and is a candidate therapeutic agent for regulating antiviral immune response in vivo. Clinical efficacy of PD-1/PD-L1 blockade awaits further experimentation with a large number of animals.

    Purpose: This study was performed to evaluate the outcome of patients with gallbladder cancer who received postoperative concurrent chemotherapy and radiation therapy. Methods and Materials: Curative resection followed by adjuvant combined modality therapy with external beam radiation therapy (EBRT) and chemotherapy was attempted in 21 consecutive gallbladder carcinoma (GBC) patients at the Mayo Clinic from 1985 through 1997. All patients received concurrent 5-fluorouracil during EBRT. EBRT fields encompassed the tumor bed and regional lymph nodes (median dose of 54 Gy in 1.8-2.0-Gy fractions). One patient received 15 Gy intraoperatively after EBRT. A retrospective analysis was performed for the end points of local control, distant failure, and overall survival. Results: After maximal resection, 12 patients had no residual disease on pathologic evaluation, 5 had microscopic residual disease, and 4 had gross residual disease. One patient had Stage I disease, and 20 had Stage III-IV disease. With median follow-up of 5 years (range: 2.6-11.5 years), 5-year survival for the entire cohort was 33%. The 5-year survival rate of patients with Stage I-III disease was 65% vs. 0% for those with Stage IV disease (p 54 Gy (microscopic residual, 3 patients; gross residual, 1 patient; negative but narrow margins, 2 patients) vs. 65% for the 15 who received a lower dose (3, gross residual; 2, microresidual; 10, negative margins). Conclusion: Patients with completely resected (negative margins) GBC followed by adjuvant EBRT plus 5-fluorouracil chemotherapy had a relatively favorable prognosis, with a 5-year survival rate of 64%. These results seem to be superior to historical surgical controls from the Mayo Clinic and other institutions, which report 5-year survival rates of approximately 33% with complete resection alone. Both tumor stage and extent of resection seemed to influence survival and local control. More aggressive measures using current cancer therapies and integration

    In this document it has met relating data to the reproduction of bovine and their handling for the man that it can serve as norms to judge reproductive efficiency but always view in the aspect of the nutritious, climatic circumstances and of handling under which met. Under the previous description one can say that the fertility is the resultant of the interaction among the inheritance, the means and the handling, they vary in particular for each region and property. The fertility can be good, regulate or bad in the measure in that the factors that intervene. The environmental effect on the reproductive processes of the cow represents 80 percent of the variation factors and they include climate, effect of the light, effect of the temperature, effect of the nutritious contribution, effect of psychological factors: the loss of the tendency to the seasonal reproduction is in fact an answer from the animals to its association with the man. The influence of the environment and the feeding of the animals are more intense in the females than in the males, being evidenced that the reproduction control is under the influence hormonal joint with the nutrition. An appropriate nutrition is prerequisite for the beginning of the sexual maturation with an appropriate weight and corporal condition. It is also described the effect and the relationship of the energy contribution about the fertility, the restart of the ovarian activity, its cause of the continuation of the interval childbirth-conception, silent ovulation, organic ancestry and interval among childbirths

    Bovine petechial fever is a Rickettsial disease of cattle, which has been diagnosed, only in Kenya, East Africa. Other countries in the region share some of the biotopes in which the disease occurs, and may well have the infection. The disease is characterised by widespread petechial and ecchymotic haemorrhages on the mucosal surfaces, and throughout the serosal and subserosal surfaces of the body organs and cavities. It may be fatal in up to 50% of untreated cases. The causal organism may be demonstrated most readily in the cytoplasm of polymorphonuclear granulocytes of the peripheral blood, as well as other leucocytes, and has been classified as Cytoecetes ondirii, a member of the tribe Ehrlichiae. Circumstantial and other evidence suggests that the disease is transmitted by an arthropod vector, which has yet to be identified. The blood of a naturally infected wild ruminant, the bushbuck, Tragelaphus scriptus has been shown to remain infective for at least 2 years, and other species such as the African buffalo, Syncercus caffer for at least 5 weeks. These and possibly other species, may serve as the amplifying and reservoir hosts.

    Objective: To study the role of gallbladder kinetics and plasma levels of gastrointestinal hormones in the mechanism of functional dyspepsia. Methods: Gallbladder ejection fractions (GBEF) were determined with 99 Tc m radionuclide imaging, and plasma levels of motilin (MTL), cholecystokinin (CCK), vasoactive intestinal peptide (VIP) and somatostatin (SS) were measured with radioimmunoassay. Thirty-two patients with functional dyspepsia of dyskinetic type (FD group) and 20 normal volunteers in control group were studied. Results: The preprandial and postprandial gallbladder ejection fractions (GBEF) and MTL levels were both obviously lower in FD group (P preprandial = 0.82, P postprandial 0.94, P 0.05), while the levels of postprandial CCK were significantly decreased in FD group (P preprandial -0.81, P postprandial = - 0.47, P 0.05). Conclusions: Patients with FD of dyskinetic type might have a significant decrease of preprandial and postprandial gallbladder emptying. The decrease of plasma levels of gastrointestinal hormones. MTL, CCK and the elevation of VIP might be the cause of slow gallbladder emptying and part of the basic pathophysiology in FD

    Full Text Available Abstract Background The objective of this study was to investigate CD9 and HMGA2 expression and its clinicopathological significance in benign and malignant lesion tissues of the gallbladder. Methods The resected specimens of 108 cases of gallbladder adenocarcinoma, 46 cases of adjacent tissue, 15 cases of polyps and 35 cases of chronic cholecystitis were made into conventional paraffin-embedded sections, using the method of EnVision immunohistochemistry to stain HMGA2 and CD9. Results HMGA2 expression of gallbladder adenocarcinoma was significantly higher than that of adenocarcinoma adjacent tissues (= 16.13, P P P P P P P P P P = 0.020, but the survival period of CD9 expression-positive cases was significantly higher than that of cases with CD9 expression-negative (P = 0.019. Cox multivariate regression analysis showed that the HMGA2 positive expression and/or CD9 negative expression was an important indicator reflecting the poor prognosis of gallbladder cancer. Conclusion The expression of HMGA2 and/or CD9 might be closely related to the carcinogenesis, clinical biological behaviors and prognosis of gallbladder adenocarcinoma.

    The aim of this study is to describe the trends and variations in the global burden of gallbladder cancer (GBC) with an emphasis on geographic variations and female gender. Data (2012-2030) relating to GBC was extracted from GLOBOCAN 2012 database and analyzed. The results of our study document a rising global burden of GBC with geographic and gender variations. The highest burden was noted in the WPRO region (based on WHO regions), Asia (based on continents) and India, Chile, and China (based on countries). The less developed regions of the world account for the majority of the global burden of GBC. The geographic variations are also present within individual countries such as in India and Chile. Females are afflicted at a much higher rate with GBC and this predilection is exaggerated in countries with higher incidence such as India and Chile. In females, people of certain ethnic groups and lower socio-economic standing are at a higher risk. Our study demonstrates a rising global burden of GBC with some specific data on geographic and gender-based variations which can be used to develop strategies at the global as well as the high-risk individual country level. © 2017 Wiley Periodicals, Inc.

    In this study, we investigated an effective strategy of treatment for unresectable gallbladder cancer (GBC) by the retrospective analysis of prognostic factors and anti-tumor therapies, especially combination therapy of arterial infusion chemotherapy and radiation therapy (AI+PT). Forty-three patients with unresectable GBC were enrolled, and prognostic factors were investigated by multivariate analysis using a proportional hazard model. In addition, we examined the indication and after-therapy by analyzing the each factor cumulative survival rates and anti-tumor effect about the AI + RT group (n=24). AI + RT and the responders to the first-line therapy were significant prognostic factors. In AI + RT group, median survival time, progression-free survival and the 1-year survival rate, the response and disease control rates was 15.5 months, 7.1 months, 62.5%. 54.2% and 95.8%, respectively; which suggested prolonged survival and high anti-tumor effect. Cumulative survival rate was significantly shorter in cases with distant metastasis except liver metastases, and has been tendency to extend in the group who underwent systemic chemotherapy as after-therapy. The treatment strategy, using the Al + RT as first-line with the systemic chemotherapy as after-therapy, suggested contribute to the prolonged survival in locally advanced and liver metastases cases of GBC.

    Chronic aflatoxin exposure has long been related to hepatocellular carcinoma (HCC). Recently, its association with gallbladder cancer (GBC) was postulated. Here we present the data supporting this hypothesis in Chile, the country with the highest GBC mortality worldwide with age-standardized mortality rates (ASMR) of 10.3 in women and 5.04 in men. The highest GBC rates occur in Southern Chile (ASMR=18), characterized by: high Amerindian ancestry, associated with high bile acid synthesis and gallstones; high poverty and high cereal agriculture, both associated with aflatoxin exposure. Aflatoxins have been detected in imported and locally grown foods items. We estimated population dietary exposure ranging from 0.25 to 35.0 ng/kg-body weight/day. The only report on human exposure in Chile found significantly more aflatoxin biomarkers in GBC than in controls (Odds Ratio=13.0). The hypothesis of aflatoxin-GBC causal link in the Chilean population is supported by: genetically-determined rapid cholesterol excretion and high gallstones prevalence (49.4%); low prevalence of HCC (ASMR=4.9) and low HBV infection (0.15%) the main co-factor of aflatoxins in HCC risk. If the association between aflatoxins and GBC were confirmed, public health interventions based on food regulation could have a substantial public health impact. Copyright © 2015 Elsevier Ltd.

    To investigate the prevalence and risk factors of polypoid lesions of the gallbladder (PLGs) in petrochemical employees in Ningbo, Zhejiang Province, China. All active and retired employees aged 20-90 years (n = 11098) of a refinery and chemical plant in eastern China were requested to participate in a health survey. The participants were subjected to interview, physical examination, laboratory assessments and ultrasonography. All the participants were invited to have a physical examination after a face-to-face interview. Fasting blood samples were obtained from the antecubital vein, and the samples were used for the analysis of biochemical values. Abdominal ultrasonography was conducted. A total of 10461 (7331 men and 3130 women) current and former petrochemical employees attended for screening. The overall prevalence of post-cholecystectomy, gallstones and PLGs was 0.9%, 5.2% and 7.4%, respectively. Compared with the increased prevalence of either gallstones or post-cholecystectomy in older persons, PLGs were more common in the middle-aged, peaking in those aged 40-59 years. Excluding the patients with gallstones, gallstones mixed with PLGs, or those who had undergone cholecystectomy, in the remaining 9828 participants, the prevalence of PLGs in men (8.9%) was significantly higher than that in women (5.5%, P employees. Male gender, HBsAg positivity, and middle age are risk factors for developing PLGs.

    Laparoscopic bile duct exploration has become one of the main options for the treatment of choledocholithiasis associated with cholelithiasis. Our objective is to describe the results of a consecutive series of patients. We retrospectively analyzed 101 (66 female/16 male) patients who underwent laparoscopic bile duct exploration. Age was 58 +/- 18 years. We analyzed operaion time, hospital stay and postoperative complications according to the surgical approach (transcystic or choledochotomy). Clinical follow up was carried out for 90 days after surgery and then subsequently by telephone. 1435 laparoscopic cholecystectomies were performed between January 1998 and December 2005. Of those, 101 of those patients underwent laparoscopic bile duct exploration for cholelithiasis and common bile duct stones. We evaluated clinical, laboratory and ultrasound predictors: 70 patients had positive and 31 negative predictors. Laparoscopic transcystic approach was successful in 78 patients and laparoscopic choledochotomy in 17 patients. Operation time was 154 +/- 59 minutes and hospital stay 4.31 +/- 3.44 days. Six patients (5.9%) were converted to open surgery. Two patients were re-operated for postoperative bile leakage. The overall effectiveness was 94%. Postoperative mortality was 0.99%. Median follow up was 51 months. Three patients died of unrelated conditions, three underwent ERCP and one had transfistular extraction for retained stones (3.96%). Laparoscopic treatment for common bile duct stones associated with gallbladder stones is a highly effective procedure with a low incidence of retained stones.

    Ultrasonography is the most valuable diagnostic tool in the evaluation of gallbladder (GB) diseases. Although sonographic findings in GB cancer have been well described, the diagnostic accuracy has not been clearly analyzed. Our purpose of this report was to discuss diagnostic difficulties and analyze causes of misdiagnosis of GB cancer based on our recent experience and so may result in more accurate diagnosis of GB cancer. We analyzed 13misdiagnosed cases out of 24 cases of GB cancer with special emphasis on diagnostic difficulties and causes of misidagnosis. The most common type of misdiagnosed GB cancer was thickened wall type which was found in 10 cases. Preoperative sonographic diagnosis of these cases was empyema in 4 cases, cholecystitis in 3, and non-specific GB wall thickening in 1. In 2 cases, any lesion could not be detected at ultrasonography. Two cases with intraluminal type of GB cancer were misdiagnosed ; one being misdiagnosed as cholecystitis with stone, and the other being completely missed. Three cases that were completely missed consist of 2 with focal wall thickening and 1 involving GB neck. In conclusion, sonographic diagnosis of GB cancer is difficult, because the wall thickening type, that mimicks the cholecystitis, is frequent. Thorough and careful investigation of GB is mandatory for eliminating misdiagnosis

    The aim of the present study was to investigate the effectiveness of laparoscopic gallbladder-preserving surgery (L-GPS) for cholelithiasis and the feasibility and value of totally laparoscopic GPS (TL-GPS). A total of 517 patients underwent L-GPS, including 365 cases of laparoscopy-assisted GPS (LA-GPS), 143 cases of TL-GPS (preservation rate, 98.3%) and nine conversions to laparoscopic cholecystectomy. The surgeries were all performed by one medical team and the mean operating time was 72 min. All macroscopic calculi were removed through endoscopy. The number of calculi observed in the patients was between one and several dozen; diameters ranged between 0.1 and 2.5 cm. Only three cases of incisional infection were noted in the LA-GPS group and long-term follow-up showed a low recurrence rate of 1.2%. L-GPS is, therefore, an excellent approach to cure cholelithiasis and TL-GPS is a feasible and effective option that could avoid incisional complications.

    To determine the association of gallbladder (GB) abnormalities on ultrasonography (US) of patients with acute hepatitis A with demographic, clinical, and biochemical factors, and with other US findings. This retrospective study was approved by our institutional review board, which waived the requirement for informed consent. We retrospectively evaluated 152 consecutive patients with acute hepatitis A who underwent US. The diagnosis of acute hepatitis A was made during acute illness by demonstrating anti- HAV of the IgM class. US images were reviewed simultaneously by two abdominal radiologists and a consensus was reached for GB wall thickening, GB collapse, lymphadenopathy, and hepatic echogenicity. The associations between demographic, clinical, biochemical, and US findings and GB wall thickening or collapse were then assessed. GB wall thickening was present in 123 (81%) and GB collapse in 96 (63%) of the 152 patients. Total bilirubin level and GB collapse differed significantly (p < 0.05) between patients with and without GB wall thickening. Gender ratio, total and peak total bilirubin level, and GB wall thickness differed significantly (p < 0.05) between patients with and without GB collapse. Multivariate analysis showed that GB wall thickening was associated with GB collapse and vice versa. GB wall thickening and GB collapse are common US abnormalities associated with each other in patients with acute hepatitis A. However, GB wall thickening or collapse is not associated with any demographic, clinical, or biochemical factors, or with other US findings, in patients with acute hepatitis A.

    Gallbladder polyps (GBP) are a common clinical finding that can express malignant potential. The aim of this study was to evaluate whether vegetarianism protects against GBP, together with other putative risk factors. A retrospective, cross-sectional study was conducted with subjects who received a health check-up from July 2005 to December 2011. Korean Buddhist priests, who are obligatory vegetarians by religious belief, were identified as vegetarians (vegetarian group) and compared with a non-vegetarian control group sampled from those coming for health check-ups at the same institution. Out of 18,483 subjects, GBP were found in 810 (4.4%). Al though GBP tended to be less common in the vegetarian group (23 [3.5%] out of 666) than in control group (787 [4.4%] out of 17,817), the difference was insignificant statistically (p=0.233). By logistic regression, old age (OR=1.61, 95% CI=1.1 9-2.26 for 30-39 years; OR=1.47, 95% CI=1.08-1.98 for 40-49 years), male gender (OR=1.51, 95% CI=1.31-1.75), high BMI (OR=1.18, 95% CI=1.00-1.39 for ≥ 23.0 kg/m(2) and vegetarianism.

    Bile from gallbladders of Arius platystomus (Singhara), Arius tenuispinis (Khagga), Pomadasys commersonni (Holoola) and Kishinoella tonggol (Dawan) were derivatised and analysed by GC-MS for identification of bile acids and bile alcohols. Cholic acid and Chenodeoxycholic acid were found as major bile acids in Arius platystomus, Arius tenuispinis and Pomadasys commersonni. Other bile acids identified in Arius platystomus were allochenodeoxycholic acid, allodeoxycholic acid, 3α,7α,12α-trihydroxy-24-methyl-5β-cholestane-26-oic acid, and 3α,7α,12α, 24-tetrahydroxy-5α-cholestane-26-oic acid. Cholesterol was found as major bile alcohol in Arius platystomus, Arius tenuispinis and Pomadasys commersonni. Cholic acid was the major bile acid identified in the bile of Kishinoella tonggol while other bile acids included 3α,7α,12α-tridydroxy-5α-cholestanoic acid and 3α,7α,12α-tridydroxy-5β-cholestanoic acid. Bile alcohol 5β-cyprinol was present in significant amounts with 5β-cholestane-3α,7α,12α,24-tetrol being the other contributors in the bile of Kishinoella tonggol.

    Loss of function of adenomatous polyposis coli (APC) has been reported in cancer. The two promoters of APC, 1A and 1B also have roles in cancer. But, the epigenetic role of APC promoters is not yet clear in gallbladder cancer (GBC) and gallstone diseases (GSD). We undertook this study to determine the epigenetic role of APC in GBC and GSD. Methylation-specific (MS)-PCR was used to analyze the methylation of APC gene. The expression of APC gene was studied by semi-quantitative PCR, real-time PCR and immunohistochemistry (IHC) in GBC, GSD and adjacent normal tissues. Of the two promoters, APC 1A promoter was found methylated in 96 per cent GBC ( P=0.0155) and 80 per cent GSD (P=0.015). Exon 1 was downregulated in grade II (P=0.002) and grade III (P=0.0001) of GBC, while exon 2 was normally expressed. Scoring analysis of IHC revealed 0 or negativity in 34.48 per cent (P=0.057) and 1+ in 24.14 per cent (P=0.005) GBC cases suggesting loss of APC expression. The present findings indicate epigenetic silencing of APC in advanced GBC. The methylation pattern, followed by expression analysis of APC may be suggested for diagnostic, prognostic and therapeutic purposes in GBC in future.

    Full Text Available Principle of oocyte cryoinjury is first overviewed and then research history of cryopreservation using bovine oocytes is summarized for the last two decades with a few special references to recent progresses. Various types of cryodevices have been developed to accelerate the cooling rate and applied to the oocytes from large domestic species enriched with cytoplasmic lipid droplets. Two recent approaches include the qualitative improvement of IVM oocytes prior to the vitrification and the short-term recovery culture of vitrified-warmed oocytes prior to the subsequent IVF. Supplementation of L-carnitine to IVM medium of bovine oocytes has been reported to reduce the amount of cytoplasmic lipid droplets and improve the cryotolerance of the oocytes, but it is still controversial whether the positive effect of L-carnitine is reproducible. Incidence of multiple aster formation, a possible cause for low developmental potential of vitrified-warmed bovine oocytes, was inhibited by a short-term culture of the postwarm oocytes in the presence of Rho-associated coiled-coil kinase (ROCK inhibitor. Use of an antioxidant α-tocopherol, instead of the ROCK inhibitor, also supported the revivability of the postwarm bovine oocytes. Further improvements of the vitrification procedure, combined with pre- and postvitrification chemical treatment, would overcome the high sensitivity of bovine oocytes to cryopreservation.

    Immunization of guinea pigs with bovine cardiac cAMP-dependent protein kinase (ATP : protein phosphotransferase, EC 2.7.1.37) resulted in the development of precipitating antibodies to the cAMP-binding subunit of the enzyme. Both the phosphorylated and nonphosphorylated cAMP-binding protein of the protein kinase reacted with the antiserum. A radioimmunoassay was developed that detects 10 ng of holoenzyme and permits measurement of enzyme concentrations in bovine cardiac muscle. Bovine liver, kidney, brain, and skeletal muscle contain protein kinases which are immunologically identical to those found in bovine cardiac muscle. However, the proportion of immunoreactive enzyme activity differed for each tissue. All of the immunologically nonreactive enzyme in skeletal muscle and heart was separable from immunoreactive enzyme by chromatography on DEAE-cellulose. Rat tissues and pig heart contained protein kinase activity that cross reacted immunologically in a nonparallel fashion with bovine cardiac enzyme. These results indicate that cAMP-dependent protein kinases within and between species are immunologically heterogeneous

    Bovine mastitis is an important animal production disease that affects the dairy industry globally. Studies have estimated the prevalence of this disease in approximately 30% of African countries, with the highest prevalence found in Ethiopia. This is despite the wide cattle distribution in Africa, and the largest number of dairy farms and herds in countries such as South Africa, Kenya and Uganda. Furthermore, the estimated financial losses due to direct and indirect impacts of bovine mastitis are lacking in this continent. Therefore, intensive research efforts will help determine the continent-wide economic impacts and advance careful monitoring of disease prevalence and epidemiology. Here, published cases supporting the occurrence and importance of bovine mastitis in certain regions of Africa are outlined.

    Bovine herpes virus 1 (BHV-1) is primarily associated with clinical syndromes such as rhinotracheitis, pustular vulvovaginitis and balanoposthitis, abortion, infertility, conjunctivitis and encephalitis in bovine species. The main sources of infection are the nasal exudates and the respiratory droplets, genital secretions, semen, fetal fluids and tissues. The BHV-1 virus can become latent following a primary infection with a field isolate or vaccination with an attenuated strain. The viral genomic DNA has been demonstrated in the sensory ganglia of the trigeminal nerve in infectious bovine rhinotracheitis (IBR) and in sacral spinal ganglia in pustular vulvovaginitis and balanoposthitis cases. BHV-1 infections can be diagnosed by detection of virus or virus components and antibody by serological tests or by detection of genomic DNA by polymerase chain reaction (PCR), nucleic acid hybridization and sequencing. Inactivated vaccines and modified live virus vaccines are used for prevention of BHV-1 infections in cattle; subunit vaccines and marker vaccines are under investigation.

    Full Text Available Abstract Background Bovine theileriosis is a common disease transmitted by ticks, and can cause loss of beef and dairy cattle worldwide. Here, an indirect enzyme-linked immunosorbent assay (iELISA based on Theileria luwenshuni surface protein (TlSP was developed and used to carry out a seroepidemiological survey of bovine theileriosis in northern China. Methods We used the BugBuster Ni-NTA His•Bind Purification Kit to purify recombinant TlSP (rTlSP, which was subsequently analyzed by Western Blotting to evaluate cross-reactivity with other pathogen-positive sera. The iELISA method based on rTlSP was successfully developed. Sera from 2005 blood samples were tested with the rTlSP-iELISA method, and blood smears from these samples were observed by microscopy. Results The specificity of iELISA was 98.9%, the sensitivity was 98.5%, and the cut-off was selected as 24.6%. Western Blot analysis of rTlSP confirmed that there were cross-reactions with Theileria luwenshuni, Theileria uilenbergi, Theileria ovis, Theileria annulata, Theileria orientalis and Theileria sinensis. The epidemiological survey showed that the highest positive rate of bovine theileriosis was 98.3%, the lowest rate was 84.1%, and the average positive rate was 95.4% by iELISA. With microscopy, the highest positive rate was 38.9%, the lowest rate was 5.1%, and the relative average positive rate was 13.7%. Conclusions An rTlSP-iELISA was developed to detect circulating antibodies against bovine Theileria in northern China. This is the first report on the seroprevalence of bovine theileriosis in northern China, and it also provides seroepidemiological data on bovine theileriosis in China.

  7. Heterogeneity of Bovine Peripheral Blood Monocytes

    2017-12-01

    Full Text Available Peripheral blood monocytes of several species can be divided into different subpopulations with distinct phenotypic and functional properties. Herein, we aim at reviewing published work regarding the heterogeneity of the recently characterized bovine monocyte subsets. As the heterogeneity of human blood monocytes was widely studied and reviewed, this work focuses on comparing bovine monocyte subsets with their human counterparts regarding their phenotype, adhesion and migration properties, inflammatory and antimicrobial functions, and their ability to interact with neutrophilic granulocytes. In addition, the differentiation of monocyte subsets into functionally polarized macrophages is discussed. Regarding phenotype and distribution in blood, bovine monocyte subsets share similarities with their human counterparts. However, many functional differences exist between monocyte subsets from the two species. In contrast to their pro-inflammatory functions in human, bovine non-classical monocytes show the lowest phagocytosis and reactive oxygen species generation capacity, an absent ability to produce the pro-inflammatory cytokine IL-1β after inflammasome activation, and do not have a role in the early recruitment of neutrophils into inflamed tissues. Classical and intermediate monocytes of both species also differ in their response toward major monocyte-attracting chemokines (CCL2 and CCL5 and neutrophil degranulation products (DGP in vitro. Such differences between homologous monocyte subsets also extend to the development of monocyte-derived macrophages under the influence of chemokines like CCL5 and neutrophil DGP. Whereas the latter induce the differentiation of M1-polarized macrophages in human, bovine monocyte-derived macrophages develop a mixed M1/M2 macrophage phenotype. Although only a few bovine clinical trials analyzed the correlation between changes in monocyte composition and disease, they suggest that functional differences between

    To investigate the feasibility of ex vivo multispectral photoacoustic (PA) imaging in differentiating cholesterol versus neoplastic polyps, and benign versus malignant polyps, of the gallbladder. A total of 38 surgically confirmed gallbladder polyps (24 cholesterol polyps, 4 adenomas, and 10 adenocarcinomas) from 38 patients were prospectively included in this study. The surgical specimens were set on a gel pad immersed in a saline-filled container. The PA intensities of polyps were then measured, using two separate wavelength intervals (421–647 nm and 692–917 nm). Mann-Whitney U test was performed for the comparison of normalized PA intensities between the cholesterol and neoplastic polyps, and between the benign and malignant polyps. Kruskal-Wallis test was conducted for the comparison of normalized PA intensities among the cholesterol polyps, adenomas, and adenocarcinomas. A significant difference was observed in the normalized PA intensities between the cholesterol and neoplastic polyps at 459 nm (median, 1.00 vs. 0.73; p = 0.032). Comparing the benign and malignant polyps, there were significant differences in the normalized PA intensities at 765 nm (median, 0.67 vs. 0.78; p = 0.013), 787 nm (median, 0.65 vs. 0.77; p = 0.034), and 853 nm (median, 0.59 vs. 0.85; p = 0.028). The comparison of the normalized PA intensities among cholesterol polyps, adenomas, and adenocarcinomas demonstrated marginally significant differences at 765 nm (median, 0.67 vs. 0.66 vs. 0.78, respectively; p = 0.049). These preliminary results indicate that benign versus malignant gallbladder polyps might exhibit different spectral patterns on multispectral PA imaging.

    The behavior of tumor markers in biliary tract malignancies is not well-known and has been scarcely studied. Such markers could play important roles in diagnostic and prognostic schemes as well as in decision-making about the best treatment strategies. This study analyzed the preoperative serum levels of conventional tumor markers (AFP, CEA, CA 19-9, CA 72-4), proliferative marker thymidine kinase (TK) and cytokeratins (TPA, TPS and CYFRA 21.1) in patients with gallbladder carcinoma, bile duct carcinoma (Klatskin) and cholangiocellular carcinoma, in relation to the patient prognosis. The study aimed in finding the role of tumor markers in not properly investigated diseases, where their importance is often marginalized. The study included 43 patients, who underwent either radical surgical procedure (n=21) or explorative laparotomy without any surgical treatment (n=22) for gallbladder carcinoma, bile duct carcinoma (Klatskin tumor) and cholangiocellular carcinoma (24, 8 and 11 patients, respectively) between 2003 and 2010 at our Department. The association of serum tumor markers and patients' prognosis were assessed for the entire cohort and for each cancer type and also with regard to treatment (radical surgery versus explorative laparotomy). Overall survival (OS) and disease-free interval (DFI) were estimated by the Kaplan-Meier method and statistically evaluated using the LogRank test. DFI was computed only in the subgroup of patients treated by radical surgery. The statistical analysis of tumor markers revealed TK as a poor prognostic factor for shorter DFI (HR=3.5, 95%CI=0.6-21.3, ptumor markers for assessment of prognosis (OS or DFI) in patients with gallbladder carcinoma, bile duct carcinoma, and cholangiocellular carcinoma.

    Patients with advanced gallbladder and biliary tract carcinoma face a dismal prognosis, as no effective palliative chemotherapy exists. The antitumor effect of gemcitabine is schedule-dependent rather than dose-dependent. We evaluated the activity of a prolonged infusion of gemcitabine in advanced gallbladder and biliary tract carcinomas. Nineteen consecutive eligible patients were enrolled. All patients were required to have histologically confirmed diagnosis and measurable disease. Gemcitabine was infused over 24 hours at a dose of 100 mg/m 2 on days 1, 8, and 15. Treatment was repeated every 28 days until progression of disease or limiting toxicity. Tumor response was evaluated every second course by computed tomography (CT) scans. Eighteen patients were evaluable for response. A total of 89 cycles of therapy were administered. One partial response was observed (6%; 95% confidence interval (CI): 0–27%) and ten additional patients had stable disease for at least two months (disease control rate 61%; 95% CI: 36–83%). The therapy was well tolerated, with moderate myelosuppression as the main toxicity. The median time to tumor progression and median overall survival was 3.6 months (95% CI 2.6–4.6 months) and 7.5 months (95% CI 6.5–8.5 months), respectively. Weekly 24-hour gemcitabine at a dose of 100 mg/m 2 is well tolerated. There was a relatively high rate of disease control for a median duration of 5.3 months (range 2.8–18.8 months). However, the objective response rate of this regimen in gallbladder and biliary tract carcinomas was limited

    The aims of the study were to describe the dynamics of the enterohepatic circulation in relation to gallbladder and gastrointestinal motility in the interdigestive as well as the postprandial period. Furthermore, to investigate the level of circulating cholecystokinin, secretin, pancreatic polypeptide, motilin and bile acids in relation to gallbladder motility and MMC during the interdigestive period. All investigations were carried out on healthy male volunteers aged 18-40 years. The most suitable method for studying various characteristics of the enterohepatic circulation, and especially gallbladder motility in humans, is scintigraphy. It is non-invasive, and allows a continuing dynamic investigation of the partitioning of the radioactive marker between the various compartment. Two entirely different pharmacological substances may be use. HIDA (diethyl-acetanilide-iminodiacetic acid) which is semisynthetic and closely related to lidocaine forms a chelate with {sup 99m}Tc for intravenous administration only. The transport of {sup 99m}Tc-HIDA across the hepatocyte is a carrier-mediated organic anion pathway, similar to the hepatic handling of bilirubin. Homocholic-acid-taurine (HCAT) is a synthetic bile acid analogue, corresponding to the naturally occurring bile acid cholic acid-taurine. It is marked with {sup 75}Se and is available for peroral use only. The {sup 75}SeHCAT is adsorbed in the same manner as the naturally occurring conjugated trihydroxy bile acids, involving specific carrier systems for absorption and secretion, i.e. with a high first pass extraction and a secretory rate proportional to the blood concentration.

    The aim of this study is to investigate the prognostic value of F-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography (PET)/computed tomography (CT) in gallbladder cancer patients. From June 2004 to June 2010, a total of 50 patients with gallbladder cancer who underwent diagnostic staging with F-18 FDG PET/CT following curative or palliative treatments were retrospectively evaluated. For the analysis, all patients were classified by age, sex, maximum standardized uptake value (SUVmax), lymph node (LN) or distant metastasis, serum level of CA19-9 and CEA, type of treatment and American Joint Committee on Cancer (AJCC) stage. The median survival for the 50 patients was 245 days and the median SUVmax in PET/CT was 8.3 (range, 0-19.7). Patients with SUVmax<6 survived significantly longer than patients with SUVmax≥6 (median 405 days vs 203 days, p = 0.0400). On Kaplan-Meier analysis, SUVmax (p =0.0400), stage (p =0.0001), CA19-9 (p =0.013), CEA (p =0.006), LN metastasis (p =0.0001), distant metastasis (p =0.0020), type of treatment (p =0.0001) were significantly associated with overall survival. Multivariate analysis study revealed that the patients with lower SUVmax measured from initial staging PET/CT (p =0.0380), no LN metastasis (p =0.0260), a lower stage (p =0.026) and curative treatment (p =0.0005) had longer survivals. The present study shows that SUVmax on F-18 FDG PET/CT can provide prognostic information in patients with gallbladder cancer.

    Full Text Available Empyema of the gallbladder develops when the gallbladder neck is obstructed in the presence of infection, preventing pus from draining via the cystic duct. Treatment options include cholecystectomy or, in patients with comorbidities, drainage via percutaneous cholecystostomy, later followed by cholecystectomy. Here, we describe a 59-year-old man who presented with complaints of recurrent hiccups and was found to have cholangiocarcinoma causing obstruction to cystic duct drainage. The patient was managed successfully by percutaneous transhepatic cholecysto-duodenal self-expandable covered metal stent.

    distinct members of the CCK/gastrin family were identified in the bullfrog (Rana catesbeiana), termed CCK and gastrin. Frog gastrin is very similar to CCK in the region defining biological activity. To evaluate whether the two endogenous peptides have distinct properties, their effects were studied...... values are 3.1 and 17.2 nM, respectively. Furthermore, gastrin had a significantly higher efficacy than CCK-8s. Thus, in spite of their close structural resemblance, there are clear differences between the two endogenous peptides in their action on gallbladder and gastric mucosa. It is concluded...

    To study the effect of emodin on protein and gene expressions of the massagers in mobility signal transduction system of cholecyst smooth muscle cells in guinea pig with cholesterol calculus. The guinea pigs were randomly divided into 4 groups, such as control group, gall-stone (GS) group, emodin group and ursodeoxycholic acid (UA) group. Cholesterol calculus models were induced in guinea pigs of GS, emodin and UA groups by lithogenic diet, while emodin or UA were given to the corresponding group for 7 weeks. The histomorphological and ultrastructure change of gallbladder were detected by microscope and electron microscope, the content of plasma cholecystokinin (CCK) and [Ca 2+ ] i were analyzed successively by radioimmunoassay and flow cytometry. The protein and mRNA of Gsα, Giα and Cap in cholecyst cells were determined by western blotting and real time polymerase chain reaction (RT-PCR). Emodin or UA can relieve pathogenic changes in epithelial cells and muscle cells in gallbladder of guinea pig with cholesterol calculus by microscope and transmission electron microscope. In the cholecyst cells of GS group, CCK levels in plasma and [Ca 2+ ] i decreased, the protein and mRNA of GS were down-regulated, the protein and mRNA of Gi and Cap were up-regulated. Emodin significantly decreased the formative rate of gallstone, improved the pathogenic change in epithelial cells and muscle cells, increased CCK levels in plasma and [Ca 2+ ] i in cholecyst cells, enhanced the protein and mRNA of Gs in cholecyst cells, reduced the protein and mRNA of Gi and Cap in cholecyst cells in guinea pig with cholesterol calculus. The dysfunction of gallbladder contraction gives rise to the disorders of mobility signal transduction system in cholecyst smooth muscle cells, including low content of plasma CCK and [Ca 2+ ] i in cholecyst cells, abnormal protein and mRNA of Gs, Gi and Cap. Emodin can enhance the contractibility of gallbladder and alleviate cholestasis by regulating plasma

    Purpose: To retrospectively evaluate CT findings of xanthogranulomatous cholecystitis (XGC) and to measure diagnostic performance for distinguishing it from gallbladder (GB) cancer. Methods and materials: Our institutional review board approved this retrospective study. Three blinded radiologists, first independently and then in consensus, retrospectively evaluated postcontrast CT images of 35 patients with histopathologically proved XGC and GB cancer, all of whom subsequently had cholecystectomy. These included 18 patients with XGC (13 male, 5 female; age range, 35-84, mean 63 years) and 17 with GB cancer (6 male, 11 female; age range, 45-95, mean 69). Differences in CT findings between XGC and GB cancer and diagnostic performances for each CT finding were calculated. Sensitivity, specificity, and accuracy were calculated for each radiologist and observer performance was also determined by receiver-operating-characteristic curve analysis. Results: Five CT findings showed significant differences between XGC and GB cancer. Sensitivity, specificity, and accuracy of each finding for the differentiation of XGC were 89%, 65%, 77% with diffuse GB wall thickening, 67%, 82%, 74% with a continuous mucosal line, 61%, 71%, 66% with intra-mural hypo-attenuated nodules, 72%, 77%, 74% with absence of macroscopic hepatic invasion, and 67%, 71%, 69% with absence of intra-hepatic bile duct dilatation, respectively. When at least three of these five CT findings were observed in combination, sensitivity, specificity, and accuracy were 83%, 100% and 91%, respectively. Sensitivities, specificities and Az values for the differentiation of XGC from GB cancer were 83%, 88%, 0.94 for reader 1, 78%, 88%, 0.93 for reader 2, and 78%, 82%, 0.84 for reader 3. Conclusions: The combination of three of the five CT findings that are common with XGC can provide excellent accuracy for the differentiation of XGC and GB cancer.

    The benefit of adjuvant therapy (AT) for gallbladder cancer (GBC) is unclear as evidenced by conflicting results from nonrandomized studies. Here we aimed to perform a meta-analysis to determine the impact of AT on overall survival (OS). We used data from MEDLINE, EMBASE and the Cochrane Collaboration Library and published between October 1967 and October 2014. Studies that evaluated AT compared with curative-intent surgery alone for resected GBC were included. Subgroup analyses of benefit based on node status, margins status, and American Joint Committee on Cancer (AJCC) staging were prespecified. Data were weighted and pooled using random-effect modeling. Ten retrospective studies involving 3,191 patients were analyzed. There was a nonsignificant improvement in OS with AT compared with surgery alone (hazard ratio [HR], 0.76; 95 % confidence interval [CI], 0.56–1.03). A significant improvement was observed in OS with chemotherapy (CT) compared with surgery alone (HR, 0.42; 95 % CI, 0.22–0.80) by sensitivity analysis. The greatest benefit for AT was also observed in those with R1 disease (HR, 0.33; 95 % CI, 0.19–0.59), LN-positive disease (HR, 0.71; 95 % CI, 0.63–0.81), and AJCC staging meeting or exceeding tumor Stage II (HR, 0.45; 95 % CI, 0.26–0.79), but not in those with LN-negative or R0 disease. Our results strongly support the use of CT as an AT in GBC. Moreover, patients with node positivity, margin positivity, or non-stage I disease are more likely to benefit from AT

    AIM: To preliminarily investigate the prognostic significance of the platelet to lymphocyte ratio (PLR) in patients with gallbladder carcinoma (GBC). METHODS: Clinical data of 316 surgical GBC patients were analyzed retrospectively, and preoperative serum platelet and lymphocyte counts were used to calculate the PLR. The optimal cut-off value of the PLR for detecting death was determined by the receiver operating characteristic (ROC) curve. The primary outcome was overall survival, which was estimated by the Kaplan-Meier method. The log-rank test was used to compare the differences in survival. Then, we conducted multivariate Cox analysis to assess the independent effect of the PLR on the survival of GBC patients. RESULTS: For the PLR, the area under the ROC curve was 0.620 (95%CI: 0.542-0.698, P = 0.040) in detecting death. The cut-off value for the PLR was determined to be 117.7, with 73.6% sensitivity and 53.2% specificity. The PLR was found to be significantly positively correlated with CA125 serum level, tumor-node-metastasis (TNM) stage, and tumor differentiation. Univariate analysis identified carcinoembryonic antigen (CEA), CA125 and CA199 levels, PLR, TNM stage, and the degree of differentiation as significant prognostic factors for GBC when they were expressed as binary data. Multivariate analysis showed that CA125 > 35 U/mL, CA199 > 39 U/mL, PLR ≥ 117.7, and TNM stage IV were independently associated with poor survival in GBC. When expressed as a continuous variable, the PLR was still an independent predictor for survival, with a hazard ratio of 1.018 (95%CI: 1.001-1.037 per 10-unit increase, P = 0.043). CONCLUSION: The PLR could be used as a simple, inexpensive, and valuable tool for predicting the prognosis of GBC patients. PMID:26074706

    We assessed population incidence rates 1998-2002 and 5-year survival rates of 317 primary gallbladder cancer (GBC) entered in the population-based cancer registry in Valdivia. We analyzed GBC incidence (Poisson regression) and GBC survival (Cox regression). Cases were identified by histology (69.4%), clinical work-up (21.8%), or death certificate only (8.8%). Main symptoms were abdominal pain (82.8%), jaundice (53.6%) nausea (42.6%), and weight loss (38.2%); at diagnosis, 64% had Stage TNM IV. In the period, 4% of histopathological studies from presumptively benign cholecystectomies presented GBC. GBC cases were mainly females (76.0%), urban residents (70.3%), Hispanic (83.7%) of low schooling Mapuche 25.0, Hispanic 16.2 (p = 0.09). The highest SIRs were in Mapuche (269.2) and Hispanic women (199.6) with 8 years of schooling. Low schooling, female and urban residence were independent risk factors. By December 31, 2007, 6 (1.9%) cases were living, 280 (88.3%) died from GBC, 32 (10.1%) were lost of follow-up. Kaplan Meier Global 5-year survival was: 10.3%, 85% at stage I and 1.9% at stage IV; median survival: 3.4 months. Independent poor prognostic factors were TNM IV, jaundice and nonincidental diagnoses. Our results suggest that women of Mapuche ancestry with low schooling (>50 years) are at the highest risk of presenting and dying from GBC and should be the target for early detection programs.

  4. Control of bovine hepatic fatty acid oxidation

    Fatty acid oxidation by bovine liver slices and mitochondria was examined to determine potential regulatory sites of fatty acid oxidation. Conversion of 1-[ 14 C]palmitate to 14 CO 2 and total [ 14 C]acid-soluble metabolites was used to measure fatty acid oxidation. Oxidation of palmitate (1 mM) was linear in both liver slice weight and incubation time. Carnitine stimulated palmitate oxidation; 2 mM dl-carnitine produced maximal stimulation of palmitate oxidation to both CO 2 and acid-soluble metabolites. Propionate (10 mM) inhibited palmitate oxidation by bovine liver slices. Propionate (.5 to 10 mM) had no effect on palmitate oxidation by mitochondria, but malonyl Coenzyme A, the first committed intermediate of fatty acid synthesis, inhibited mitochondrial palmitate oxidation (inhibition constant = .3 μM). Liver mitochonndrial carnitine palmitoyltransferase exhibited Michaelis constants for palmitoyl Coenzyme A and l-carnitine of 11.5 μM and .59 mM, respectively. Long-chain fatty acid oxidation in bovine liver is regulated by mechanisms similar to those in rats but adapted to the unique digestive physiology of the bovine

    Full Text Available INTRODUCTION: Glutaraldehyde-treated crimped bovine pericardial grafts are currently used in aortic graft surgery. These conduits have become good options for these operations, available in different sizes and shapes and at a low cost. OBJECTIVE:To evaluate the results obtained with bovine pericardial grafts for aortic reconstruction, specially concerning late complications. METHOD: Between January 1995 and January 2002, 57 patients underwent different types of aortic reconstruction operations using bovine pericardial grafts. A total of 29 (50.8% were operated on an urgent basis (mostly acute Stanford A dissection and 28 electively. Thoracotomy was performed in three patients for descending aortic replacement (two patients and aortoplasty with a patch in one. All remaining 54 underwent sternotomy, cardiopulmonary bypass and aortic resection. Deep hypothermia and total circulatory arrest was used in acute dissections and arch operations. RESULTS: Hospital mortality was 17.5%. Follow-up was 24.09 months (18.5 to 29.8 months confidence interval and complication-free actuarial survival curve was 92.3% (standard deviation ± 10.6. Two patients lately developed thoracoabdominal aneurysms following previous DeBakey II dissection and one died from endocarditis. One "patch" aortoplasty patient developed local descending aortic pseudoaneurysm 42 months after surgery. All other patients are asymptomatic and currently clinically evaluated with echocardiography and CT scans, showing no complications. CONCLUSION: Use of bovine pericardial grafts in aortic reconstruction surgery is adequate and safe, with few complications related to the conduits.

    Full Text Available Bovine Herpesvirus type 5 (BoHV-5 has not been conclusively demonstrated to cause bovine abortion. Brain lesions produced by Neospora caninum and Bovine Herpesvirus type 1 (BoHV-1 exhibit common features. Therefore, careful microscopic evaluation and additional diagnostic procedures are required to achieve an accurate final etiological diagnosis. The aim of the present work was to investigate the occurrence of infections due to BoHV-1, BoHV-5 and N. caninum in 68 cases of spontaneous bovine abortions which showed microscopic lesions in the fetal central nervous system. This study allowed the identification of 4 (5.9% fetuses with dual infection by BoHV-5 and N. caninum and 33 (48.5% cases in which N. caninum was the sole pathogen identified. All cases were negative to BoHV-1. The results of this study provide evidence that dual infection by BoHV-5 and N. caninum occur during pregnancy in cattle; however, the role of BoHV-5 as a primary cause of bovine abortion needs further research. Molecular diagnosis of BoHV-5 and N. caninum confirmed the importance of applying complementary assays to improve the sensitivity of diagnosing bovine abortion.

    Full Text Available The recently emerging atypical bovine pestiviruses have been detected in commercial foetal bovine serum (FBS of mainly South American origin so far. It is unclear how widely the viruses are presented in commercial FBS of different geographic origins. To further investigate the possible pestivirus contamination of commercially available FBS batches, 33 batches of FBS were obtained from ten suppliers and analysed in this study for the presence of both the recognised and the atypical bovine pestiviruses. All 33 batches of FBS were positive by real-time RT-PCR assays for at least one species of bovine pestiviruses. According to the certificate of analysis that the suppliers claimed for each batch of FBS, BVDV-1 was detected in all 11 countries and BVDV-2 was detected exclusively in the America Continent. The atypical pestiviruses were detected in 13 batches claimed to originate from five countries. Analysis of partial 5'UTR sequences showed a high similarity among these atypical bovine pestiviruses. This study has demonstrated, for the first time that commercial FBS batches of different geographic origins are contaminated not only with the recognised species BVDV-1 and BVDV-2, but also with the emerging atypical bovine pestiviruses.

    2013-06-01

    Gallbladder cancer (GBC) is an aggressive neoplasm associated with late diagnosis, unsatisfactory treatment and poor prognosis. Previous work showed that connective tissue growth factor (CTGF) expression is increased in this malignancy. This matricellular protein plays an important role in various cellular processes and its involvement in the tumorigenesis of several human cancers has been demonstrated. However, the precise function of CTGF expression in cancer cells is yet to be determined. The aim of this study was to evaluate the CTGF expression in gallbladder cancer cell lines, and its effect on cell viability, colony formation and in vitro cell migration. CTGF expression was evaluated in seven GBC cell lines by Western blot assay. Endogenous CTGF expression was downregulated by lentiviral shRNA directed against CTGF mRNA in G-415 cells, and the effects on cell viability, anchorage-independent growth and migration was assessed by comparing them to scrambled vector-transfected cells. Knockdown of CTGF resulted in significant reduction in cell viability, colony formation and anchorage-independent growth (P cancer may confer a growth advantage for neoplastic cells. © 2013 The Authors.

    This study was designed to determine the prevalence of gallstones in the last three years and evaluate the associated risk factors in the population who underwent health screening. Although there are many studies reporting the prevalence and risk factors of GB polyp, the results varied among each report. The aims of this study were to evaluate the prevalence rate and risk factors of GB polyp, colon polyp and fatty liver in the population who underwent health screening. The study population consisted of 4,877 visited the health promotion center in Dalseogu, Daegu in Korea from January 2011 to December 2013. Each participant in the study had their biliary system gallbladder examined using ultrasonography. The prevalence of GB polyp was evaluated along with age, gender, metabolic syndrom, body mass index (BMI), Fatty liver, Colon polyp. A showed of total 383 (7.9%) people were found to have GB polyps. The prevalence of sex among 256 (9.8%) patients men and 127 (5.6%) women which showed significantly higher in male than in female subjects(p=0.001). The mean size of the GB polyps 4.92 mm (1.6-17 mm). The sizes of most GB polyps (73.6%) were less than 10 mm in diameter. 122 subjects (31.28%) had multiple GB polyps which 2 or more polyps and 261 subjects (68.2%) had single polyp. Independent risk factors related with GB polyp were male gender (OR 0.551, p<0.001), overweight that BMI above 23 kg/m{sup 2} (OR 0.713, p=0.002) triglyceride (OR 0.571, p<0.001), metabolic syndrome (OR 0.049, p=0.033) and colon polyp (OR 1.409, p=0.002). In spite of the conclusion, the prevalence GB polyp was higher than previous Korea and other country reports. The GB polyp in a healthy population was results as 7.9%. The risk factors of GB polyps were found to be male, being overweight, triglyceride, metabolic syndrome and colon polyp. Not only the subject of a health examination is needed but, a further study of the general public when possible.

The sizes of most GB polyps (73.6%) were less than 10 mm in diameter. 122 subjects (31.28%) had multiple GB polyps which 2 or more polyps and 261 subjects (68.2%) had single polyp. Independent risk factors related with GB polyp were male gender (OR 0.551, p<0.001), overweight that BMI above 23 kg/m"2 (OR 0.713, p=0.002) triglyceride (OR 0.571, p<0.001), metabolic syndrome (OR 0.049, p=0.033) and colon polyp (OR 1.409, p=0.002). In spite of the conclusion, the prevalence GB polyp was higher than previous Korea and other country reports. The GB polyp in a healthy population was results as 7.9%. The risk factors of GB polyps were found to be male, being overweight, triglyceride, metabolic syndrome and colon polyp. Not only the subject of a health examination is needed but, a further study of the general public when possible

    Full Text Available Latin Americans are highly heterogeneous regarding the type of Native American ancestry. Consideration of specific associations with common diseases may lead to substantial advances in unraveling of disease etiology and disease prevention. Here we investigate possible associations between the type of Native American ancestry and leading causes of death. After an aggregate-data study based on genome-wide genotype data from 1805 admixed Chileans and 639,789 deaths, we validate an identified association with gallbladder cancer relying on individual data from 64 gallbladder cancer patients, with and without a family history, and 170 healthy controls. Native American proportions were markedly underestimated when the two main types of Native American ancestry in Chile, originated from the Mapuche and Aymara indigenous peoples, were combined together. Consideration of the type of Native American ancestry was crucial to identify disease associations. Native American ancestry showed no association with gallbladder cancer mortality (P = 0.26. By contrast, each 1% increase in the Mapuche proportion represented a 3.7% increased mortality risk by gallbladder cancer (95%CI 3.1-4.3%, P = 6×10-27. Individual-data results and extensive sensitivity analyses confirmed the association between Mapuche ancestry and gallbladder cancer. Increasing Mapuche proportions were also associated with an increased mortality due to asthma and, interestingly, with a decreased mortality by diabetes. The mortality due to skin, bladder, larynx, bronchus and lung cancers increased with increasing Aymara proportions. Described methods should be considered in future studies on human population genetics and human health. Complementary individual-based studies are needed to apportion the genetic and non-genetic components of associations identified relying on aggregate-data.

    This overview comments on gender-specific differences in incidence, risk factors and prognosis in patients with carcinoma of the liver, gallbladder, extrahepatic bile duct and pancreas. For the literature review, the MEDLINE database (PubMed) was searched under the key words "liver cancer", "gallbladder cancer", "extrahepatic bile duct carcinoma", "pancreatic cancer" AND "gender". There were significant gender differences in the epidemiology of the analysed carcinomas. The incidence of hepatocellular carcinoma (HCC) is much higher in men than in women, one of 86 men, but only 1 out of 200 women develop a malignant primary liver tumour in Germany in the course of their life. The lifetime risk for carcinomas of the gallbladder and extrahepatic bile ducts in Germany amounts to about 0.6 % for women and 0.5 % for men, specifically gallbladder carcinomas are observed more frequently in women than in men. For pancreatic cancer, no clear gender preference exists in Germany, although the mortality risk for men is higher than that for women (age-adjusted standardised death rate in men 12.8/100, 000 persons, in women 9.5). Remarkable is furthermore the shift of the tumour incidence in the last decades. Liver cancer has increased among men in Germany by about 50 % in the last 30 years, the incidence of gallbladder carcinoma has inversely dropped. The prognosis of these cancers across all tumour stages is uniformly bad in an unselected patient population. This is probably the main reason why only little - if any - gender differences in survival are described. In addition to avoiding the known risk factors such as hepatitis B and C virus infection, alcohol abuse, and smoking, the avoidance of overweight and obesity plays an increasingly important role in the prevention of these cancers.

    Aims: To evaluate clinical outcomes in patients with typical biliary pain, normal ultrasonic findings, and a positive 99m technetium (Tc)-labelled hepatic iminodiacetic acid analogue (HIDA) scintigraphy with cholecystokinin (CCK) provocation indicating gallbladder dyskinesia, as per Rome III criteria, undergoing laparoscopic cholecystectomy (LC). Methods and materials: Consecutive patients undergoing LC for gallbladder dyskinesia were identified retrospectively. They were followed up by telephone interview and review of the electronic case records to assess symptom resolution. Results: One hundred consecutive patients (median age 44; 80% female) with abnormal gallbladder ejection fraction (GB-EF <35%) were followed up for a median of 12 months (range 2–80 months). Following LC, 84% reported symptomatic improvement and 52% had no residual pain. Twelve percent had persisting preoperative-type pain of either unchanged or worsening severity. Neither pathological features of chronic cholecystitis (87% of 92 incidences when histology available) nor reproduction of pain on CCK injection were significantly predictive of symptom outcome or pain relief post-LC. Conclusion: In one of the largest outcome series of gallbladder dyskinesia patients in the UK with a positive provocation HIDA scintigraphy examination and LC, the present study shows that the test is a useful functional diagnostic tool in the management of patients with typical biliary pain and normal ultrasound, with favourable outcomes following surgery. - Highlights: • Gallbladder dyskinesia (GD) is a challenging condition to diagnose and treat. • This study evaluated clinical outcomes following laparoscopic cholecystectomy (LC). • There was sustained symptomatic benefit in >80% following surgery. • Pre-operative counselling before LC is important

    Full Text Available Abstract Background Gallbladder cancer typically follows an aggressive course, with chemotherapy the standard of care for advanced disease; complete remissions are rarely encountered. The epidermal growth factor receptor (EGFR is a promising therapeutic target but the activity of single agent oral EGFR tyrosine kinase inhibitors is low. There have been no previous reports of chemotherapy plus an EGFR-tyrosine kinase inhibitor (TKI to treat gallbladder cancer or correlations of response with the mutation status of the tyrosine kinase domain of the EGFR gene. Case presentation A 67 year old man with metastatic gallbladder cancer involving the liver and abdominal lymph nodes was treated with gemcitabine (1000 mg/m2 on day 1 and 8 every 21 days as well as daily erlotinib (100 mg. After four cycles of therapy, the CA 19-9 normalized and a PET/CT showed a complete remission; this response was maintained by the end of 12 cycles of therapy. Gemcitabine was then discontinued and single agent erlotinib was continued as maintenance therapy. The disease remains in good control 18 months after initiation of therapy, including 6 months on maintenance erlotinib. The only grade 3 toxicity was a typical EGFR-related skin rash. Because of the remarkable response to erlotinib plus gemcitabine, we performed tumor genotyping of the EGFR gene for response predicting mutations in exons 18, 19 and 21. This disclosed the wild-type genotype with no mutations found. Conclusion This case report demonstrates a patient with stage IV gallbladder cancer who experienced a rarely encountered complete, prolonged response after treatment with an oral EGFR-TKI plus chemotherapy. This response occurred in the absence of an EGFR gene mutation. These observations should inform the design of clinical trials using EGFR-TKIs to treat gallbladder and other biliary tract cancers; such trials should not select patients based on EGFR mutation status.

    Full Text Available Abstract Background Many important agricultural traits such as weight gain, milk fat content and intramuscular fat (marbling in cattle are quantitative traits. Most of the information on these traits has not previously been integrated into a genomic context. Without such integration application of these data to agricultural enterprises will remain slow and inefficient. Our goal was to populate a genomic database with data mined from the bovine quantitative trait literature and to make these data available in a genomic context to researchers via a user friendly query interface. Description The QTL (Quantitative Trait Locus data and related information for bovine QTL are gathered from published work and from existing databases. An integrated database schema was designed and the database (MySQL populated with the gathered data. The bovine QTL Viewer was developed for the integration of QTL data available for cattle. The tool consists of an integrated database of bovine QTL and the QTL viewer to display QTL and their chromosomal position. Conclusion We present a web accessible, integrated database of bovine (dairy and beef cattle QTL for use by animal geneticists. The viewer and database are of general applicability to any livestock species for which there are public QTL data. The viewer can be accessed at http://bovineqtl.tamu.edu.

    Experiments using bovine semen reveal that the addition of a high-gain water soluble dye results in random laser action when excited by a Q-switched, frequency doubled, Nd:Yag laser. The data shows that the linewidth collapse of the emission is correlated to the sperm count of the individual samples, potentially making this a rapid, low sample volume approach to count determination.

    A RIA method was developed for identifying the presence of serum antibodies to the bovine leukosis virus. The chosen procedure uses the ability of the virus antigen to bind to the solid phase of a polystyrene carrier. The method was compared with the ELISA method and with the pseudoneutralization and immunodiffusion tests. A high level of agreement was achieved between the RIA and the ELISA methods (95%). By its accuracy the RIA method proves superior to the immunodiffusion test. (author)

    Bovine mastitis is a costly disease in dairy cattle worldwide. As of yet, the control of bovine mastitis is mostly based on prevention by thorough hygienic procedures during milking. Additional strategies include vaccination and utilization of antibiotics. Despite these measures, mastitis is not fully under control, thus prompting the need for alternative strategies. The goal of this study was to isolate autochthonous lactic acid bacteria (LAB) from bovine mammary microbiota that exhibit beneficial properties that could be used for mastitis prevention and/or treatment. Sampling of the teat canal led to the isolation of 165 isolates, among which a selection of ten non-redundant LAB strains belonging to the genera Lactobacillus and Lactococcus were further characterized with regard to several properties: surface properties (hydrophobicity, autoaggregation); inhibition potential of three main mastitis pathogens, Staphylococcus aureus, Escherichia coli and Streptococcus uberis; colonization capacities of bovine mammary epithelial cells (bMEC); and immunomodulation properties. Three strains, Lactobacillus brevis 1595 and 1597 and Lactobacillus plantarum 1610, showed high colonization capacities and a medium surface hydrophobicity. These strains are good candidates to compete with pathogens for mammary gland colonization. Moreover, nine strains exhibited anti-inflammatory properties, as illustrated by the lower IL-8 secretion by E. coli-stimulated bMEC in the presence of these LAB. Full genome sequencing of five candidate strains allowed to check for undesirable genetic elements such as antibiotic resistance genes and to identify potential bacterial determinants involved in the beneficial properties. This large screening of beneficial properties while checking for undesirable genetic markers allowed the selection of promising candidate LAB strains from bovine mammary microbiota for the prevention and/or treatment of bovine mastitis.

    The aim of this study was to analyze the effect of roselle extract solution on the microstructure and hardness of bovine enamel. Ten bovine teeth and a 5% concentration of roselle extract solution were prepared. Immersions of each bovine tooth in roselle extract solution were conducted up to 60 minutes. The bovine enamel surface was characterized in hardness and microscopy. It was apparent that the initial hardness was 328 KHN, and after immersion in 15 and 60 min, the values decrease to 57.4 KHN and 11 KHN, respectively. Scanning electron microscopy (SEM) revealed changes in enamel rods after immersion in the roselle extract solution.

    Radiographs and CT images taken during oral cholecystography in dogs were interpreted in an independent, blind fashion by three radiologists on two occasions and visual assessment of gallbladder density compared to the actual CT values. While there was significant intra- and inter-observer variation, the mean scores for the observers' interpretations of both radiographs and prints correlated well with the actual CT values (p > 0.05). In five out of six comparisons between first and second readings, the observers gave a lower score on the second reading. The considerable variation reflects the problems inherent in subjective evaluation of agents that produce small but measurable differences in radiographic density. Studies involving such subjective data have to be carefully designed in order to obtain meaningful results

    2018-01-01

    Full Text Available Intravascular large B-cell lymphoma is a rare subtype of extranodal diffuse B-cell lymphoma characterized by proliferation of neoplastic cells within the lumen of small and medium sized vessels. Clinical and imaging findings are nebulous as the intravascular subtype of lymphoma can involve a multitude of organs. Involvement of the gallbladder is extremely uncommon, and imaging findings can be easily confused for more prevalent pathologies. We report a case of intravascular large B-cell lymphoma in an 83-year-old male and review clinical presentation and imaging findings on CT, ultrasound, hepatobiliary iminodiacetic acid (HIDA scan, and MRI. It is important for the radiologist to know about this disease as the imaging findings are atypical of other types of lymphoma, and this may lead to a delay in diagnosis and treatment.

    Full Text Available Abstract Background The inactivation of the tumour suppressor gene and activation of the proto-oncogene are the key steps in the development of the human cancer. The p53 and c-erbB-2 are the best examples of it. In the present study, our aim was to determine the role of these genes in the carcinogenesis of gallbladder by immunohistochemistry. Methods In all 78 consecutive patients of gall bladder diseases were studied for p53 and c-erbB-2 expression immunohistochemically and their expression was correlated with the age, grades and stages of the disease and presence of stone. An informed consent was obtained in each case. Chi square and z test were applied to see the association of p53 and c-erbB-2 over expression with other clinicopathological factors. Results Eight (20% patients of gall bladder cancer were positive for p53 expression and 10 (25% patients for c-erbB-2. The p53 positivity increased with increasing grade while cerbB-2 positivity decreased with increasing grade of gall bladder cancer. Mean age in cerbB-2 positive cases were lesser as compared to negative cases while p53 did not show such association with age. Conclusion Only one case of gall bladder cancer co-expressed the p53 and c-erbB-2, thereby suggesting that p53 and c-erbB-2 may have independent role in carcinogenesis of gall bladder cancer. c-erbB-2 over expression in adenoma and younger age group indicates its role as an early event in carcinogenesis of gallbladder. However study of larger sample is required to further validate the results.

    Fibromyalgia, a chronic syndrome of diffuse musculoskeletal pain and somatic hyperalgesia from central sensitization, is very often comorbid with visceral pain conditions. In fibromyalgia patients with gallbladder calculosis, this study assessed the short and long-term impact of laparoscopic cholecystectomy on fibromyalgia pain symptoms. Fibromyalgia pain (VAS scale) and pain thresholds in tender points and control areas (skin, subcutis and muscle) were evaluated 1week before (basis) and 1week, 1,3,6 and 12months after laparoscopic cholecystectomy in fibromyalgia patients with symptomatic calculosis (n = 31) vs calculosis patients without fibromyalgia (n. 26) and at comparable time points in fibromyalgia patients not undergoing cholecystectomy, with symptomatic (n = 27) and asymptomatic (n = 28) calculosis, and no calculosis (n = 30). At basis, fibromyalgia+symptomatic calculosis patients presented a significant linear correlation between the number of previously experienced biliary colics and fibromyalgia pain (direct) and muscle thresholds (inverse)(pfibromyalgia pain significantly increased and all thresholds significantly decreased at 1week and 1month (1-way ANOVA, pFibromyalgia pain and thresholds returned to preoperative values at 3months, then pain significantly decreased and thresholds significantly increased at 6 and 12months (pfibromyalgia patients undergoing cholecystectomy thresholds did not change; in all other fibromyalgia groups not undergoing cholecystectomy fibromyalgia pain and thresholds remained stable, except in fibromyalgia+symptomatic calculosis at 12months when pain significantly increased and muscle thresholds significantly decreased (pfibromyalgia symptoms and that laparoscopic cholecystectomy produces only a transitory worsening of these symptoms, largely compensated by the long-term improvement/desensitization due to gallbladder removal.

    Gallbladder cancer (GBC) is a lethal cancer with poor prognosis associated with high invasiveness and poor response to chemotherapy and radiotherapy. New therapeutic approaches are urgently needed in order to improve survival and response rates of GBC patients. We screened 130 small molecule inhibitors on a panel of seven GBC cell lines and identified the HSP90 inhibitor 17-AAG as one of the most potent inhibitory drugs across the different lines. We tested the antitumor efficacy of 17-AAG and geldanamycin (GA) in vitro and in a subcutaneous preclinical tumor model NOD-SCID mice. We also evaluated the expression of HSP90 by immunohistochemistry in human GBC tumors.In vitro assays showed that 17-AAG and GA significantly reduced the expression of HSP90 target proteins, including EGFR, AKT, phospho-AKT, Cyclin B1, phospho-ERK and Cyclin D1. These molecular changes were consistent with reduced cell viability and cell migration and promotion of G2/M cell cycle arrest and apoptosis observed in our in vitro studies.In vivo, 17-AAG showed efficacy in reducing subcutaneous tumors size, exhibiting a 69.6% reduction in tumor size in the treatment group compared to control mice (p < 0.05).The HSP90 immunohistochemical staining was seen in 182/209 cases of GBC (87%) and it was strongly expressed in 70 cases (33%), moderately in 58 cases (28%), and weakly in 54 cases (26%).Our pre-clinical observations strongly suggest that the inhibition of HSP90 function by HSP90 inhibitors is a promising therapeutic strategy for gallbladder cancer that may benefit from new HSP90 inhibitors currently in development.

    To develop a software tool for quantification of liver and gallbladder function, and to assess the repeatability and reproducibility of measurements made with it. The software tool developed with the JAVA programming language uses the JAVA2 Standard Edition framework. After manual selection of the regions of interest on a 99mTc hepatic iminodiacetic acid study, the program calculates differential hepatic bile flow, basal duodeno-gastric bile reflux (B-DGBR), hepatic extraction fraction (HEF) of both the lobes with deconvolutional analysis and excretion half-time with nonlinear least squares fit. Gallbladder ejection fraction, ejection period (EP), ejection rate (ER), and postcholecystokinin (CCK) DGBR are calculated after stimulation with CCK-8. To assess intra-observer repeatability and intra-observer reproducibility, measurements from 10 normal participants were analyzed twice by three nuclear medicine technologists at the primary center. To assess inter-site reproducibility, measurements from a superset of 24 normal participants were also assessed once by three observers at the primary center and single observer at three other sites. For the 24 control participants, mean+/-SD of hepatic bile flow into gallbladder was 63.87+/-28.7%, HEF of the right lobe 100+/-0%, left lobe 99.43+2.63%, excretion half-time of the right lobe 21.50+6.98 min, left lobe 28.3+/-11.3 min. Basal DGBR was 1.2+/-1.0%. Gallbladder ejection fraction was 80+/-11%, EP 15.0+/-3.0 min, ER 5.8+/-1.6%/min, and DGBR-CCK 1.3+/-2.3%. Left and right lobe HEF was virtually identical across readers. All measures showed high repeatability except for gallbladder bile flow, basal DGBR, and EP, which exhibited marginal repeatability. Ejection fraction exhibited high reproducibility. There was high concordance among the three primary center observers except for basal DGBR, EP, and ER. Concordance between the primary site and one of the other sites was high, one was fair, and one was poor. New United States

    To evaluate the utility of signal intensity differences between in-an opposed-phase MRI and the lipid peak ratio in-vivo proton MR spectroscopy of the gallbladder as diagnostic tools for measuring the lipid content f gallbladder bile. Twenty-six normal volunteers underwent MR imaging (FMPSPGR) and in-vivo proton MR spectroscopy of the gallbladder. In all cases the results of liver function tests were normal, as were cholesterol levels, and ultrasonography of the gaubladder revealed nothing unusual. For MRI and MRS a 1.5T unit (Signa Horizon; GE Medical System, Milwaukee, U.S. A.) was used. In-phase and opposed-phase coronal-section MR images (FMPSPGR; TR=125 msec, TE=1.8, 4.2 msec) of the gallbladder were obtained, and differences in signal intensity thus determined. For proton MR spectroscopy of the gallbladder, a localized proton STEAM sequence was employed. A single voxel of 1-8 cm 3 was placed at the center of the gallbladder cavity, peak areas at 0.8-1.6 ppm (lipid), 2.0-2.4 ppm, 3.2-3.4 ppm, 3.9-4.1 ppm, and 5.2-5.4 ppm were measured by peak areas at 0.8-1.6 ppm (lipid), 2.0-2.4 ppm, 3.2-3.4 ppm, 3.9-4.1 ppm, and 5.2-5.4 ppm were measured by proton MRS and the relative peak area ratios of peak 0.8-1.6 ppm/other peaks were calculated. The degree of correlation between signal intensity differences at MRI and the relative peak area ratio of lipid in proton MRS was estimated using the p-value and Pearson's correlation coefficient. Signal intensity differences ranged from 11.3 to 43.4 % (mean, 26 ±8.9%), and the range of lipid peak area ratio at MRS was 0.10-0.97 (mean, 0.66 ±0.21). There was significant correlation between the two measured values (p=0.014, Pearson's correlation coefficient =0.478). In normal cystic bile, signal intensity differences at in-and opposed-phase MRI and relative lipid peak area ratios at MRS varied, though both methods could be used diagnostically for measuring the lipid contents of body tissue
